Jenrick stated that Badenoch's refusal to remove Truss, following her 'disastrous mini-Budget', was a key reason for his decision to join Nigel Farage's party.
He was sacked from the Conservative front bench last week, with Badenoch alleging he was 'secretly plotting' his defection.
Jenrick criticised the Conservative Party, asserting it had 'betrayed its voters and members' and was 'in denial' about its record.
Badenoch, in contrast, has maintained that Britain remains a successful country, attempting to draw a clear distinction with Reform UK.
