Kemi Badenoch has insisted she would reverse any measures in the Government’s post-Brexit reset that “damaged the interests of the United Kingdom”. The Tory leader is set to meet Pedro Serrano, the EU’s representative to the UK, in London on Monday.

In a letter to Mr Serrano Mrs Badenoch said the Conservatives “would take back any legislative or judicial powers handed over to the EU by the present government” if returned to power. Her party is said to be concerned about planned concessions on freedom of movement and fisheries.

Sir Keir Starmer has used his first 10 months in Government to try to strengthen ties with the EU. He is also set to host a UK-EU summit on 19 May in the UK capital.

But Mrs Badenoch said: “I will make it my mission to take back every power he hands over to Brussels.” She has also claimed that the Prime Minister’s reset “isn’t worth the paper it’s written on”.

In the letter, first reported by the Telegraph, Mrs Badenoch wrote: “It is important that I stress that the next Conservative government under my leadership would not remain bound by terms that failed the five tests set out above, and damaged the interests of the United Kingdom and its people.”
