And where did say he will trigger A50 the day after the referenda?

On the diplomacy, the idea that other European countries would be ready to start a second negotiation is for the birds. Many are under pressure for what they have already agreed. Then there is the legality. I want to spell out this point carefully, because it is important. If the British people vote to leave, there is only one way to bring that about, namely to trigger article 50 of the treaties and begin the process of exit, and the British people would rightly expect that to start straight away. Let me be absolutely clear about how this works. It triggers a two-year time period to negotiate the arrangements for exit. At the end of this period, if no agreement is in place, then exit is automatic unless every one of the 27 other EU member states agrees to a delay.

David Cameron on triggering Article 50
Before the ballot, Mr Cameron told Parliament: “If the British people vote to leave, there is only one way to bring that about, namely to trigger Article 50 of the treaties and begin the process of exit, and the British people would rightly expect that to start straight away.”
Indeed, his own Treasury’s analysis of what might happen in the event of our departure from the EU was based on the assumption that the process would begin immediately after the vote.
But he reneged on this promise after the referendum, leaving the job to his successor, Theresa May — who eventually began the formal process of leaving the EU some nine months later.
And there are various articles that mention David Cameron’s pledge, after he resigned. So lets not pretend that history is any different.
