The Queen of Spain chaired the VI Educational Congress of the Federación Española de Enfermedades Raras FEDER (Spanish Federation of Rare Diseases) at the CEIBas Guadalentín. El Paretón, district of Totana, Murcia.  FEDER was established in 1999 to represent and defend the rights of people with rare diseases.

The conference is part of the CREDIBLE project, which seeks to share good practices among teachers from different European countries so that they have the tools with which to improve socio-educational attention. During the round table families and the national and international educational community transferred the value of 'technological innovation' and the possibilities for the rural environment in educational inclusion for an individualised response to minors with rare and undiagnosed diseases.

​Before leaving, Her Majesty toured some of the classrooms where she conversed with tutors, classmates and teachers, of students with rare diseases.

The Queen of Spain chaired a working meeting with The Urgent Spanish Foundation -FundéuRAE (La Fundación del Español Urgente) on Tuesday at the Royal Spanish Academy, Madrid. 

The FundéuRAE is a non-profit organisation founded in February 2005, the result of an agreement between the EFE Agency and the BBVA bank, with the advice of the Royal Spanish Academy (RAE), whose main objective is to promote the good use of Spanish in the media. Its team of journalists, linguists, lexicographers, orthotypegraphers, proofreaders and translators offer recommendations and answers daily queries, to aid those who use the language in their work.

Her Majesty has followed the work of FundéuRAE since 2005 and accepted her honorary presidency in January 2021. Queen Letizia was informed of the projects and works in development that the Foundation plans to carry out in 2021 including the potential points on the new edition of the Language and Journalism Congress, which will take place after the summer in San Millán de la Cogolla.

​The King and Queen of Spain presided over acts of celebration on World Book Day at the headquarters of the Instituto Cervantes in Alcalá de Henares (Madrid), the hometown of Miguel de Cervantes.

After the initial greetings, the King and Queen moved to the central patio where readings were read and a video was screened of the poet Francisco Brines Bañó, Miguel de Cervantes 2020 prize winner, reading a poem. Their Majesties saw the exhibition 'Los Libros de Jesús Munarriz' in the Patrimonial Library of the Cervantes Institute and unveiled a commemorative plaque marking their visit. Before leaving they conversed with guests; including authors and editors.

The idea 'Book Day' originated from Spanish writer Vicente Clavel Andrés as a way to honour Miguel de Cervantes (author of Don Quixote), first on the 7th of October, his birth date, then on the 23rd of April, his death date. In 1995 UNESCO decided that World Book and Copyright Day, would be celebrated on the 23rd of April, the date is thought to be the anniversary of the death of Miguel de Cervantes, William Shakespeare and Inca Garcilaso de la Vega. 

The King and Queen of Spain, accompanied by their daughters, Leonor, Princess of Asturias and Infanta Sofía presided over the launching ceremony of the Submarine S-81 'Isaac Peral', at the Navantia shipyard in Cartagena, Murcia.

The Submarine S-81 'Isaac Peral', is the first of four submarines of the S-80 series destined for the Spanish Navy, placing Spain in a relevant role within the countries capable of building and designing submarines. The ship resulting from this project is considered one of the most advanced conventional submarines (non-nuclear) in the world. It is, therefore, a clear commitment to national technological development, which will enhance the strategic independence of the country's defence and the international projection of the Spanish industrial fabric. 

After the initial greetings, the Spanish Royal Family saw a plaque commemorating their visit, spoke with workers who participated in the construction of Submarine S-81 'Isaac Peral' and toured the shipyard's engineering plant and the Virtual Design Centre (CDV). 

At the launching ceremony of the Submarine S-81 'Isaac Peral' King Felipe VI and Leonor, Princess of Asturias, cut the ribbon which released a sacrificial bottle, as established by maritime tradition. After the National Anthem, the family were photographed with the crew of the submarine.

The Queen of Spain was at the headquarters of The Ministry of Industry, Trade and Tourism on Friday to attend a presentation of the report conducted by the 'Working Group' on "Women and Internationalization of the Spanish Economy".

The Working Group was launched in 2019 by the Secretary of State for Trade within the framework of the II Action Plan to Support Internationalization and within the Internationalization Strategy of the Spanish Economy 2017-2027.  ​It is made up of representatives of the government administrations as well as university institutions and the business sector, in order to identify problems and find joint solutions.

At the event, ​Her Majesty was presented with the findings of the Working Group report on “Women and Internationalization” and heard how more promotion is need to encourage greater participation of women in international activity. The report highlighted the importance of promoting greater visibility and training, the incorporation of gender clauses in trade agreements, and greater financial support for women. 

The Queen of Spain participated in a virtual event organised by the Princess of Girona Foundation (FPdGi) to announce the winner of the 2021 'Social' FPdGi Award.

Before announcing Ousman Umar, social entrepreneur and founder of NASCO Feeding Minds as the winner of the 2021 Social Award, Her Majesty hosted four previous years winners in her office at the Palace of Zarzuela to discuss the importance of social enterprises.​

Between the 4th of March and 29th of April, the FPdGi begins a virtual tour of different autonomous communities of Spain (La Rioja, Castilla-La Mancha, Aragon & the Valencian Community) to publicise the activity of its programs, propose current debates and announce the new winners for 2021 in Arts and Letters, Business, Social field and Scientific Research. In addition, in each territory, the Entrepreneurial Challenge with educational centres, an online disruptive workshop that encourages creative innovation, teamwork and communication based on a guided dynamic of generating ideas about a related problem, which has been energized four weeks before.

On Tuesday, The King and Queen of Spain had two engagements in Madrid.  At Zarzuela Palace, Their Majesties received Hugh Elliott, the ambassador of the United Kingdom in Spain, to whom they conveyed their condolences on the death of Prince Philip, The Duke of Edinburgh. ​

His Royal Highness, aged 99 passed away on 9th April 2021 and was the longest-serving consort of a reigning British monarch. 

Later in the day, Their Majesties attended the presentation ceremony for the launch of the new IFEMA brand, at the IFEMA Municipal Palace. 

IFEMA 'Institución Ferial de Madrid' (Fair Institution of Madrid) is an entity charged with the organisation of fairs, halls and congresses in their facilities in Madrid. The new corporate identity is identified with IFEMA's determination to evolve its business model, expand and diversify its revenue streams, generate opportunities and alliances to boost its presence in new markets, in addition to giving value and significance to the Madrid brand.

Today, Queen Letizia premiered a pleated skirt by Adolfo Domínguez.  

The cream midi length skirt features soleil pleats with a fine black contrast.

Letizia teamed it with a black sleeveless top with a mock neck.

I initially thought it was her Hugo Boss 'Fasmine' knit shell top but this new style doesn't have the same side ribbing detail or extended sleeve as the 'Fasmine' model. Furthermore, the top appears to have a double ribbed trim around the arm opening.

The finely ribbed mock neck does appear to match the knit top Letizia wore in September of 2018.

Separating the top and the skirt was her black ​Burberry ruffle leather waist belt.

Letizia complemented the monochrome ensemble with her black Nina Ricci 'Arc' leather clutch and Manolo Blahnik BB snakeskin-embossed pumps with a custom rubber platform sole ​(repeat).

She finished the outfit with her dazzling diamond teardrop earrings.

The Queen of Spain presided over an act of tribute to Clara Campoamor, at the Congress of Deputies, Madrid.

Clara Campoamor Rodríguez 1888 -1972 was a Spanish politician and feminist who is best known for her advocacy for women's rights and suffrage during the writing of the Spanish Constitution of 1931. Campoamor's advocacy led to the inclusion of constitutional language that sought to guarantee equality between men and women. 

The Congress begins celebrations of the 90th anniversary of the approval of the female vote in Spain with a tribute to Clara Campoamor. Campoamor's desk and some personal belongings, donated to Congress, have been moved to the room of the Palace that bears her name.

After the initial greetings, Her Majesty saw a bust of Clara Campoamor, her desk, documents and personal items from her office. Later in the 'Salón de los Pasos Perdidos' (Hall of Lost Steps) successive interventions took place by the First Vice President of the Government and the Presidents of the Senate and Congress who highlighted the importance of paying tribute to Clara Campoamor.

The King and Queen of Spain inaugurated the Iberdrola Innovation and Training Campus under the theme RETO (Challenge) 'Recovery, Energy, Transition and SDG' and delivered the Supplier of the Year Awards, at San Agustín del Guadalix, Madrid.

The Iberdrola group is a global energy leader, the first wind power producer and one of the largest electricity companies by market capitalisation in the world. The Iberdrola Innovation and Training Campus has state-of-the-art facilities which represent Iberdrola's commitment to technology, R&D and collaboration with technology centres to lead the energy transition, green recovery and the employability of young people and senior professionals in sectors of the future. Approximately 13,000 people receive training development in its classrooms annually.

After the initial greetings, Their Majesties moved to the auditorium where the 'CHALLENGE COVID Special Mention Awards' and 'Iberdrola RETO Awards' were presented. Afterwards, King Felipe VI and Queen Letizia toured the Campus, signed the book of honour and were photographed by the commemorative plaque marking their visit.

Queen Letizia stepped out in a new olive green pant suit for the visit to the Iberdrola campus.

The separates are from Spanish fashion brand, Bimba Y Lola.  The set consists of a double-breasted blazer with peaked lapels, and high-rise straight-cut trousers.

The Spanish Queen softened the masculine suit with a black camisole featuring a scallop lace trim.

She carried the ​Nina Ricci 'Marche' handbag with a snakeskin-embossed flap front.

On her feet were the black Prada Saffiano patent pointy-toe pumps.

Letizia finished the look with her Gold & Roses Double Dagger Earrings.

The Queen of Spain held a working meeting with the Mutua Madrileña Foundation at their headquarters in Madrid.
