It's open Tory warfare in the Commons. David Cameron is throwing a string of barbs undermining Boris Johnson's apparent suggestion there could be a second referendum after a No vote. Every line is being met by a shake of the head by the London Mayor. Arms are firmly folded. Labour MPs - for once - are the ones hollering "more!" Extraordinary stuff in the Commons. Labour MPs cheer on Cameron and shout 'more, more' as he demolishes Boris Johnson. Strange times #Brexit — Steven Swinford (@Steven_Swinford) February 22, 2016 As for Michael Gove, the Justice Secretary who also backed Brexit over the weekend, he is nowhere to be seen on the front bench. Mr Cameron finishes his statement with a clear barb at Boris: "I'm not standing for re-election. I have no other agenda..." Ben Riley-Smith, Political Correspondent
