Here is the full text of David Davis’s resignation letter to Theresa May:
It is more than two years since the British people voted to leave the European Union on an unambiguous and categorical promise that if they did so they would be taking back control of their democracy.
They were told they would be able to manage their own immigration policy, repatriate sums of UK cash currently spent by the EU, and, above all, that they would be able to pass laws independently and in the interests of the people of this country.
Brexit should be about opportunity and hope. It should be a chance to do things differently, to be more nimble and dynamic, and to maximise the particular advantages of the UK as an open, outward-looking global economy.
The dream is dying, suffocated by needless self-doubt.
