The UK's 'reset' with the European Union is just the beginning, Lord Mandelson has said, following the Prime Minister's deal with Brussels.

The Ambassador to the US failed to rule out rejoining the bloc in the future as he spoke about the agreement yesterday.

His comments come after Keir Starmer was accused of a Brexit 'surrender' last week after agreeing to make concessions on EU fishing rights and plans to introduce a youth mobility scheme.

In a speech to the Atlantic Council think-tank in Washington, Lord Mandelson said the Prime Minister had embarked on a reset to improve the 'miserable' deal with which the UK left the EU.

He said the agreement would 'finish the job' and 'tie up some loose ends which we've done in trade, energy co-operation, police and border security and intelligence sharing and now, of course, in defence.'
