DEFINING what Brexit actually means will only strengthen the forces of The Hun, Theresa May has warned.

Accusing those demanding greater clarity on the issue of ‘appeasement’, she insisted: “That is just what Fritz wants us to do.”

She said: “Now is the time to ‘keep mum’.

“There are Germans within our midst. Who’s that chap in your local pub, standing on his own at the end of the bar, trying to look inconspicuous but listening intently to your every word?

“Confront him. Ask him who won the FA Cup in 1976. If he does not know the answer immediately, you will know he is a ‘Jerry’ and you must then chase him down the street.”

May added: “If Frau Merkel and her henchmen get wind of the Grand Plan then Germany will conquer our proud island, leading to thousands of decent Britons being forced into high quality manufacturing jobs.”
