"Cameron has already consigned himself to the longest obituary in political history, given that he is a relatively young man, by delivering the Brexit vote. Hard to imagine, but his legacy may be worse than Blair’s. And not a single realistic UK politician will want to join him by being seen as the person who guarantees we leave. No wonder Johson and Gove look so sheepish: they realise just how disastrous is the situation that they have created and do not want to share Cameron’s fate.
But there is another reason why no knew will want start the Article 50 process and the EU has already exposed its hand here. It wants the UK to go quickly and so wants Article 50 invoked now. But precisely because doing so gives them all the negotiating power no one in the UK will want to do that. After all, once Article 50 is invoked the EU can say no to absolutely anything the UK suggests, wait two years and see the UK leave empty handed and there would be literally nothing the UK could do about it."
