Brexit news latest: EU formally adopts three-month extension as Donald Tusk warns 'it may be the last one'

The EU27 has formally adopted the three-month Brexit extension, Donald Tusk has said as he warned it "may be the last one".

The EU council president said the delay until January 31 has now been adopted, before he urged British politicians to "make the best use of this time".

He wrote on Twitter: "The EU27 has formally adopted the extension. It may be the last one.

"Please make the best use of this time.

"I also want to say goodbye to you as my mission here is coming to an end. I will keep my fingers crossed for you."

It comes after Boris Johnson formally agreed to the extended deadline, signing a document which was sent to Mr Tusk agreeing to the EU's terms.

In a letter to Mr Tusk, the Prime Minister reluctantly accepted the delay, saying he had no choice under British law.

"This unwanted prolongation of the UK's membership of the EU is damaging to our democracy," he said.

"I would also urge EU member states to make clear that a further extension after 31st January is not possible. This is plenty of time to ratify our deal."

The PM also admitted his fears about Parliament's continued resistance to his deal and states it is the reason for him trying to secure a general election.

Today, Boris Johnson accused MPs of trying to delay Brexit "forever" in a combative speech after Jeremy Corbyn said Labour would back a general election.

The Prime Minister said a "new and revitalised" Parliament was needed to take Britain out of the European Union as he introduced legislation for a poll on December 12.

Mr Johnson took aim at Mr Corbyn's previous opposition to an election, and claimed Labour was not interested in delivering Brexit.

"All they want to do is procrastinate," he told the Commons. "They don't want to deliver Brexit on October 31, on November 31, even on January 31."
