Nigel Farage will tell his fledgling party on Friday to prepare for power as soon as 2027 – as he warns the financial markets could foreclose on Labour's spendthrift Government and force an early election.
Mr Farage, whose Reform UK has topped the polls for months, will issue the alert in a speech to his annual conference in Birmingham.
In an exclusive interview with the Daily Mail ahead of the conference, the former City trader highlighted the rising borrowing costs being forced on Labour by sceptical financial markets.
And he predicted that a new party formed by Jeremy Corbyn could splinter Labour and help hasten the Government's demise.
'I think they may struggle to last the course,' he said. 'The financial situation is very, very grim. The bond markets, just every single day there is a loss of confidence. I was with a couple of big Wall Street guys last night and confidence in the UK is ebbing. If I'm right about the temptation of the Left for many Labour MPs, they may well struggle to get through another couple of years.
