With a parliamentary term lasting up to five years that could see Sir Keir retaining the Downing Street keys until around 2034.Only 19 per cent of the public do not expect Labour to record two successive victories.The poll makes depressing reading for Mr Sunak – but indicates that the rise of Mr Farage, bidding to win his first Commons seat, also has serious implications for Labour.He is the clear choice of both the public, and crucially Conservative supporters, to be next Tory leader if as expected the party loses on July 4 and Mr Sunak resigns.Asked to choose a successor from a list comprising the six current Tory leadership favourites and the Reform Party leader, Mr Farage wins among both groups.Only Commons Leader Penny Mordaunt runs him close.Among the electorate as a whole, 19 per cent want Mr Farage as next Conservative leader, followed by Ms Mordaunt on 15 per cent. None of James Cleverly, Kemi Badenoch, Suella Braverman, Priti Patel and Robert Jenrick polled more than six per cent.Mr Farage is even further ahead with those who voted Conservative in 2019. A total of 22 per cent of this group want him to be next Tory leader, with Ms Mordaunt on 16 per cent and the rest way behind.Nigel Farage has caused a stir by entering the general election campaign (James Manning/PA) More
