A delegation of Brexit supporters will present the EU's chief negotiator with a hamper of English sparkling wine, cheddar cheese and Shakespeare plays at a meeting in Brussels today, as they warn him against under-estimating Britain's global influence.

The group, led by MEP Steven Woolfe, hopes to foster a more positive tone in the negotiations - but will also use the meeting with Michel Barnier to warn of "huge support" among voters for a "no deal" scenario where Britain reverts to WTO rules.

Mr Woolfe will be joined this morning by former CBI head Lord Digby Jones, Labour Leave chairman John Mills, and former British Chamber of Commerce chief John Longworth as they discuss Brexit with Mr Barnier.

A source said they planned to present the gifts to Mr Barnier in a Fortnum and Mason hamper which would also contain a jar of marmalade, a bottle of English cider and a biography of Winston Churchill.
