Donald Franciszek Tusk is a Polish politician who has been the President of the European Council since 2014. He served as Prime Minister of Poland from 2007 to 2014 and was a co-founder and chairman of the Civic Platform political party.
The PM said "nobody relished" going to the polls weeks before Christmas But this Parliament had "run its course" and was "incapable" of settling Brexit.
The PM has formally accepted the EU's offer of a Brexit extension until 31 January 2020 agreed earlier on Monday .
, he said it was an "unwanted prolongation".
Urging the EU to rule out any further extension, he said there was time to ratify his Brexit deal But he feared the current Parliament would never do so "as long as it has the option of further delay".
The PM's acceptance means that the UK will not leave the EU on Thursday - despite a "do or die" promise he repeatedly made during this summer's Tory leadership campaign and since taking office In July .
EU Council President Donald Tusk said what was being offered was a "flextension" - meaning the UK could leave before the deadline if a deal was approved by Parliament.
It Comes as MPs prepare to vote on the PM's proposals for an early general Election on 12 December. The SNP and Lib Dems have also proposed an Election - on 9 December. The vote is expected after 1900 GMT.'Run and hide'
In response, Mr Corbyn said he backed an Election But only after certain conditions were met - including legal confirmation of the extension and reassurances that students wouldn't be "disenfranchised" by the mid-December date because they had left for the Christmas holidays.
A No 10 source said the government would introduce a bill "almost identical" to the Lib Dem/SNP option on Tuesday if Labour voted their plan down later, and "we will have a pre-Christmas Election anyway".
The SNP's Westminster leader Ian Blackford said it would only support a poll "on its terms" and suggested this could depend on 16 and 17-year olds and EU nationals being given the vote.
The Lib Dem/SNP plan does not include a new timetable for his Legislation - the Withdrawal Agreement Bill.
The BBC's political editor, Laura Kuenssberg , said she understands the government has offered to fix the Election date on 12 December, But a Lib Dem source told her they were holding firm to their date, adding: "If we are doing this, we are not doing it on the government's terms. "
Over half of the applications - 58% - were from voters aged 34 or under, compared to just 7% for those over 65. The swell coincided with Mr Johnson's first proposal, in early September, for a snap Election .
The EU is also attaching some extra wording to the extension - including a reminder for the UK that, until it leaves, it remains a fully paid up member of the EU, including all the rights and obligations that go along with membership.
After the extension has been signed off This Week , Brussels will watch, arms folded from the sidelines as the next moves are decided in Westminster.
The SNP and Lib Dems have broken with the Labour position on Brexit to push for an Election on 9 December.
If passed, it would enable an Election to take place with only a majority of one, rather than two-thirds of MPs.
Lib Dem leader Jo Swinson said while her preference was for another referendum, there was not enough support in Parliament for this as things stood.
A general Election , she told MPs, was the only way to stop Mr Johnson pushing through his Brexit deal in the coming weeks "on the back of Labour votes".
"Leaving EU is The Thing that will wreck their future. "
The leader of The Independent Group for Change, former Conservative MP Anna Soubry , sent an email to her party's supporters accusing the SNP and Lib Dems of "turning their backs" on the People's Vote campaign.
The Independent Group for Change has five MPs.
