A commemorative 50p coin stamped with the 29 March exit date has now been stopped in its tracks as it is confirmed the UK will not be leaving the bloc on Friday.

The unique treat was confirmed in the Chancellor’s Budget in October, unveiling a “Friendship with all nations" slogan on the reverse side.

The public, as with Brexit, will now have to wait a little longer.

A Best for Britain spokesperson said: “Another day, another sterling pr cock-up for this woeful government.

"Talking up a commemorative coin for a completely arbitrary leaving date was never going to be a mint decision.

“The country has been short-changed by Brexit."

The Treasury has said no coins dated 29 March have been produced for sale and that a test batch which had been created had come at “no cost” to the taxpayer.

A HM Treasury spokeswoman said: “The commemorative 50 pence coin to mark the UK leaving the European Union will be made available following our departure.

“Those who are interested in buying this commemorative coin can register their interest on the Royal Mint website as with other commemorative coins.”
