Tory MPs hate each other. They aren’t even trying to hide it any more. They’ve abandoned all but the most basic civility. Right there in the chamber, before the press, the public and the TV cameras, they heckle, taunt and deride each other with unbridled contempt.

It must be bliss, right now, to be a Labour MP. Each day you can just stroll into the Commons, lie back on your comfy green bench, and watch the Conservative Party tear itself apart, right before your eyes.

This evening saw the latest reading of the customs bill. The debate almost immediately disintegrated into a rhetorical punch-up, with Tory Remainers on one side, and Tory Brexiteers on the other.

Anna Soubry, a Tory Remainer, started by paying tribute to Margaret Thatcher for her commitment to the single market. Sir Edward Leigh, a Tory Brexiteer, crashed into her speech like a rhino into a wendy house.

“I knew Margaret Thatcher!” he bellowed. “I worked for Margaret Thatcher! And [Ms Soubry] ain’t no Margaret Thatcher!”

“Pathetic!” squawked Nicky Morgan, a Tory Remainer, straight back at him. “Is that the best you can do?”

“Wholly unnecessary,” sniffed Ms Soubry. “And really rather foolish.”

“Rather than talking about the detail, he prefers to trade insults!” snapped Ms Morgan, fixing Sir Edward with a glare that could have burnt through a breezeblock.
