Watch: Could the Tories do a deal with Reform?
Conservative MP Alex Burghart has said Reform "wants to destroy" his party but refused to definitively rule out a deal between the two sides in the future.
It comes after Reform UK topped a YouGov opinion poll for the first time this week, edging in front of Labour on 24% and the Tories on 21%.
Conservatives Lord Craig Mackinlay and Sir Jacob Rees-Mogg have called for the party to make a pact with Reform to boost its chances at the next election.
