[No deal is the] ultimate fall back [and needs to be prepared for] so that our partners are convinced that this is a deadly serious negotiation - Michael Fallon

Our security rests on Nato. No one seriously disputes that. Britain will never be part of an EU army.

All those involved should be investigated now to find out who this leaker is. Ministers are subject to the Official Secrets Act just like anybody else. It is an offence to divulge secret information from the most secret of all government bodies, which is the National Security Council. It has got to be stopped.

We need some alternative arrangements for Northern Ireland - some of that technology is already in place - we need the right to exit the backstop if the negotiations fail, we need some improvements to the political declaration. These aren't the biggest things, but what they do require is some optimism and ambition and above all some energy. We will have a fresh team, a fresh prime minister and there is no reason at all why this can't be done in the next three months.
