The Boris Johnson campaign has been very quiet this week. But as I say in The Sun this morning, it will move into a higher gear next week. Liz Truss is set to become the first person who sits round the Cabinet table to endorse the former Foreign Secretary. I understand that the campaign will also unveil a slew of endorsements from MPs, giving it more declared supporters than any other campaign.
One MP who won’t be endorsing him, though, is Amber Rudd. Her and Boris Johnson sat down on Thursday. But ultimately the differences between them over Brexit policy are simply too great to make any kind of dream ticket work.
I understand that Rudd pushed the former Foreign Secretary to budge on his commitment that the UK would leave the EU on October 31st with or without a deal. But Johnson would not. Rudd felt that she couldn’t support someone holding this position.
Another complication was that Johnson and Rudd’s differences on Brexit policy made it very hard for them to agree on a joint governing agenda.
