We must work within "the possible" "D" and our options are limited due to the EU red line on FOM....I think we must be prepared to walk away and leave it to the remaining nations to put forward THEIR terms.

Mr Corbyn can raise his political stature and profile by putting the country first, and to be honest he really has no alternative.
