Charles Wellesley, 9th Duke of Wellington

In 2021 he put forward an amendment to the Environment Bill to attempt to reduce pollution from the dumping of sewage in rivers. The initial amendment was rejected by MPs - which led to a backlash on social media. The Environment Secretary George Eustice proposed making measures a legal duty but Wellington put forth the amendment again to attempt to ensure changes came into force.

In September 2015, he was elected to a seat in the House of Lords as a Conservative in a by-election following the retirement of Lord Luke. On 4 September 2019, he quit the Conservative Party. He sat as a "non-affiliated" member of the House of Lords from September 2019 to September 2020. Since September 2020 he has sat as a Crossbench Peer.

Wellington is also the 10th Duke of Ciudad Rodrigo ("Duque de Ciudad Rodrigo") of the Kingdom of Spain, which on 10 March 2010 was ceded to him by his father. In accordance with Spanish procedure, Wellington (then styled as Marquess of Douro) made a formal claim to the title with the Spanish Ministry of Justice. King Juan Carlos of Spain, through his minister, granted the succession to the Dukedom of Ciudad Rodrigo to Wellington in May 2010.

On 1 October 2007, he became Chairman of the Governing Council of King's College London, an institution of which his wife Princess Antonia is an alumna, and of which his ancestor Arthur Wellesley, 1st Duke of Wellington, was instrumental in the foundation.

Wellington has worked for a number of non-profit or charitable organisations. He was a patron of British Art at the Tate Gallery (1987–90), a member of the Royal College of Art between (1992–97), Chair of British-Spanish Tertulias (1993–98) and Trustee of the Phoenix Trust from 1996 to 2001). He was appointed OBE in 1999 for services to British-Spanish business relations. He was appointed a Deputy Lord-Lieutenant of Hampshire in 1999. In 2003 he was given a four-year appointment as a Commissioner for English Heritage.

He married Princess Antonia of Prussia on 3 February 1977 at St. Paul's Church, Knightsbridge, London. The couple are friends of King Charles III and Queen Camilla.
