All six of Cornwall’s newly elected MPs swore their oath of allegiance in Cornish in the House of Commons on Tuesday.

Labour MPs Anna Gelderd, Jayne Kirkham, Noah Law and Perran Moon made their affirmations in Cornish as well as in English, as did Liberal Democrats Andrew George and Ben Maguire.

Members of both Houses of Parliament have to take an oath of allegiance to the Crown using a religious text or make a non-religious affirmation by law.

The oath must first be made and taken in English and members can follow this with an oath in Welsh, Scottish Gaelic or Cornish, the law stipulates.

Perran Moon, the new MP for Camborne and Redruth, said on X: “Delighted and honoured to have been sworn in as MP but can’t disguise my disappointment that ‘for legal purposes’ I had to do the affirmation in English first and Cornish second.”

MPs take the oath by holding a sacred text and saying the words: “I swear by Almighty God that I will be faithful and bear true allegiance to His Majesty King Charles, his heirs and successors, according to law. So help me God.”

MPs cannot take their seat, speak in debates, vote or receive a salary until taking the oath or affirmation.

The Conservative candidates lost all six Cornish seats in the general election, with four going to Labour, and two to the Liberal Democrats.

Labour claimed the constituencies of St Austell and Newquay and South East Cornwall for the first time.
