Reminders of banished Reform UK defector were all around the Conservative party conference in Birmingham

As Kemi Badenoch basked in the applause of the Tory faithful at the close of her pivotal speech at Conservative party conference last year, one member of her shadow cabinet looked less than enthused.

Robert Jenrick, bested by Badenoch in the leadership contest a year earlier, looked on, and – as one shadow cabinet member now recalls – had to be prodded by Lord Ashcroft to applaud. “If you’re plotting against someone, then you at least pretend to like them,” they say. “The thing about Robert is he’s not even a good machiavellian.”
