Conservative MP Danny Kruger has become the latest politician to switch allegiances to Reform UK to lead "preparing for government" team.
Kruger, who has been an MP since 2019 and was latterly shadow minister for work and pensions, said the Conservative party is "over".
The BBC reports Kruger said there were points at which he was proud to represent the Tory party, but added: "The rule of our time in office was failure.
"Bigger government, social decline, lower wages, higher taxes and less of what ordinary people actually wanted.
"This is my tragic conclusion, the Conservative Party is over, over as a national party, over as the principal opposition to the left."
He said he was "honoured" to have been asked to help Reform prepare for government and hoped Farage would be the next PM.
Conservative leader Kemi Badenoch said: "I can't be distracted by that, and I'm not going to get blown off course by these sort of incidents.
"I know this is the sort of thing that is going to happen while a party is changing. I'm making sure people understand what Conservative values are."
