Donald Tusk has secured his re-election as President of the European Council.
EU leaders voted overwhelmingly in favour of Mr. Tusk by 27-to-1 to provide him with a two-and-a-half-year term in office.
His term will end in November 2019.
The 27 leaders who voted in his favour consisted of British Prime Minister Theresa May and Hungarian Prime Minister Viktor Orban, who has become an outspoken critic of the EU.
Prime Minister Joseph Muscat of Malta, which currently holds the EU presidency, said the former Polish PM 'will work with each and every one of us.'
Despite this, his native country of Poland attempted to block his bid for EC President.
'Make the EU better'
This challenge comes amidst a dispute with the Polish Government that he exceeded his mandate by intervening in their politics.
Their conservative Prime Minister, Beata Szyldo, wrote to May and other EU leaders, pleading with them to oust her former rival.
However, the former Polish politician will now play a significant part in the Brexit negotiations.
Other challenges that the EU faces include the ongoing refugee crisis and ISIS.
He later tweeted: 'I will do my best to make the EU better.'
The brawl between the Pole and Ms Szyldo's Law and Justice Party led to his native country providing an opponent to the EC role- Polish MEP Jacek Saryusz-Wolski.
But the right-wing Polish party fear that his re-election will contribute towards the end of the EU.
'Destablising the EU'
According to the AFP news agency, Szyldo added that countries that fail to comprehend the founding principles of the EU are 'destablising it.'
Though she did not reveal her voting intentions beforehand, May's spokesman said she welcomed the appointment and believed that the Pole was doing a good job.
This comes amidst suggestions that the UK might abstain from the vote.
This is Mrs May's final EU summit before she triggers Article 50 this month.
Brexit was excluded from the agenda of the EU Summit. But they will discuss Britain's departure at a meeting on Friday.
German Chancellor Angela Merkel, who is a staunch ally of the former Polish politician, said his re-election will bring a period of stability to the superbloc.
Who is Donald Tusk?
The former Polish prime minister remained in office during 2007-2014. He led the centre-right Civic Platform when the PiS was in power.
But PiS blame him for the death of Polish president Lech Kaczynski during a plane crash in 2010.
It is believed Mr. Tusk's government attempted to cover-up the investigation into the crash.
The European Council meets two times every year. It consists of the leaders of the 28 EU member states. They discuss issues regarding treaty changes, foreign, justice and home affairs.
It is different to the European Council of Ministers, which enables ministers from different EU countries to gather and pass legislation on specific policies. For example, the UK Chancellor will meet with his financial counterparts to legislate new economic policies.
Tusk's current term of office will end in May 2017 to coincide with the Brexit talks.
