The outgoing-European Council President Donald Tusk has said his final goodbye to Britain, in an official capacity.
On Tuesday, he tweeted to confirm the bloc had granted the UK its latest extension to the Brexit process.
The so-called 'flextension' means the deadline for the UK to leave the EU is now set at January 31st.
However, the country will be able to leave earlier if it passes the withdrawal agreement through the British parliament.
Meanwhile MPs have voted for an early general election there, going to the polls on December 12th.
The UK House of Commons voted by an overwhelming majority of 438 to 20 in favour of an election in little more than six weeks' time.
It is set to be dominated by debate over the UK's departure from the EU.
British Labour leader Jeremy Corbyn, who had withheld his party's support for an election until Tuesday, claimed the ballot would be a "once-in-a-generation chance to transform our country".
Liberal Democrat leader Jo Swinson claimed the election would be the "best chance to elect a government to stop Brexit".
Tuesday's vote was British Prime Minister Boris Johnson's fourth attempt to take the UK to the polls since he took office three months ago.
He finally won the support of opposition parties for an early election, after making a reluctant request to the EU for a three-month delay to Brexit.
But Mr Tusk seems to have washed his hands of it, to some degree.
He said: "To my British friends, 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."
