There are times when I almost feel sorry for Theresa May. She is clearly trying her best to deliver something impossible, while being shot by both sides. It’s hard not to sympathise with that.

And then I remember that she didn’t have to rush into triggering Article 50. And could have published the research into the likely effects of Brexit. She could have been honest with the public, and communicated more directly with us all the way, and possibly even given us an informed choice at the end of it.

But no, like Cameron before her, she gambled on political advantage, tried to use the referendum as a tool to strengthen her parliamentary position, and then failed in that and in her negotiations with Europe.

Like Cameron she has ridden the Brexit beast into political disaster, one by trying to end it, one by trying to deliver it.

History will not be kind to these two PMs.
