The Prime Minister was in good spirits as she joked around with other helpers while handing out water to thirsty runners at the Easter 10 race. She has just come back from a walking holiday in the Welsh mountains with her husband, Philip, as Parliament continues its Easter recess after Britain was granted a delay to leaving the EU. The Prime Minister was in good spirits as she joked around with other helpers while handing out water to thirsty runners at the Easter 10 race Mrs May's spokesman denied she would use the trip to plot a new election as an escape - as she did on her last holiday at Easter 2017. Back at Westminster the race to replace the PM is hotting up, with Tory rivals including Boris Johnson, Sajid Javid and Jeremy Hunt jostling for position to take the top spot. The leadership hopefuls were yesterday warned by Britain's former EU ambassador against pledging to tear up Mrs May's Brexit deal, as this would 'wreck any prospect' of a future trade pact with the EU. Sir Ivan Rogers, who stood down from his role in January 2017, said he was a 'little bit surprised' the UK was not further down the exit process as he spoke to BBC Two's Newsnight programme. He said the public still do not know what the Prime Minister thinks, and would not say if he would vote for her deal if he was an MP, saying it was 'difficult to see a path through' the current negotiations to a short-term solution. On who should succeed her as Conservative leader, he said the party will likely want a 'true believer' to take over.

'So if people were to give commitments, saying 'when I'm in power, if you give me this job, I will reopen the Withdrawal Agreement', and indicate we can't possibly accept the backstop and take a much more robust and bellicose position with Brussels - well, that leads fairly inexorably to a breakdown of the talks.' The Tories are also gearing up to fight the European elections, with two MEPs campaigning for a second referendum among those re-selected as candidates. Mrs May has said she is determined to get a Brexit deal through Parliament before the elections so that voting can be cancelled, but this is looking increasingly unlikely. A heavy defeat would likely precipitate calls for Mrs May to quit. Share or comment on this article: All rights reserved for this news site dailymail and under his responsibility
