The phrase "a vote for Reform is a vote for Labour" has emerged as a focal point of the Conservative Party's campaign, as it contends with the rising support for Nigel Farage's party.
But does a vote for Reform really block the Tories?
According to the latest polling by Electoral Calculus, Reform UK is set to gain from the Conservatives.
Seat projections suggest Reform leads Labour by 8 per cent in the Ashfield constituency - and the Conservatives, from which Lee Anderson dramatically defected, by a staggering 21.6 points.

The poll shows Reform at 37 per cent, followed by Labour at 30.7 per cent, and the Tories at 15.4 per cent.
In response, Reform candidate Lee Anderson said: "Vote Reform. Then you get Reform."
It comes after the Prime Minister warned that a vote for Farage's party would hand electoral victory to Labour.
Farage's return to frontline politics has split support among right-of-centre voters, further damaging Sunak's hopes of winning Thursday's election.
Do you think if you vote Reform you get Reform in the 2024 election?GettyThe Tories said that if 130,000 voters joined Liam Booth-Isherwood, the Reform UK candidate who switched to back the Conservatives, “it would be enough to stop Labour’s supermajority”.
A Conservative Party spokesperson said: "There is no doubt, only a vote for the Conservatives can prevent an unaccountable majority for Labour, and the ruin this would bring for the country."
75 per cent of GB News members who voted in the poll think that if you vote for Reform in the General Election, you'll get Reform.
21 per cent on the other hand disagreed, while four per cent are unsure.
