European Parliament are bidding farewell to UK colleagues ahead of a final vote on the Brexit deal,UK will leave the bloc on Friday at 23:00 GMT.
The withdrawal agreement is expected to be signed off at the historic session of the 751-member assembly in Brussels.
Some MEPs have marked the occasion with songs others wore “always united” scarves. President of the European Commission Ursula von der Leyen told the UK “We will always love you.”
Departing British members are expected to be serenaded by their colleagues in a special ceremony after the vote, which is due at 17.00 GMT.
MEPs expected to ratify terms of Brexit deal after a debate, setting in stone Britain’s exit from the bloc on Friday.
Some 751 members of the European Parliament from 28 member states are widely expected to usher in the final stage of the ratification process.
UK Prime Minister Boris Johnson has stressed that the transition period should not go beyond one year, ending at the end of 2020, but European leaders and members of the British opposition say that deadline is unachievable.
Some British politicians have suggested Brussels might be flexible on its rules to protect trade flows in talks.

In recent days, European politicians have stepped up their rhetoric, calling on the UK to be willing to compromise.
Foreign Minister Heiko Maas said the UK will have to compromise on issues such as consumer rights and environment protection if it wants to maintain full access to the EU’s single market.
“By the end of the year, we need to be clear on the shape of our relationship,” Mass said.
“So let me say very openly Yes, we all want zero tariffs and zero trade barriers, but that also means zero dumping and zero unfair competition. Without similar standards to protect our workers, our consumers and the environment, there can be no full access to the largest single market in the world.”
On Monday, Michel Barnier, the EU’s chief negotiator, said the bloc will “never, never, never” compromise on the integrity of its single market, saying London must now face reality after underestimating the costs of leaving.
“Leaving the single market, leaving the customs union will have consequences. And what I saw in the last year, is that many of these consequences have been underestimated in the UK.”
Barnier said while Brussels was willing to be flexible and pragmatic in trade talks, Britain’s choices have made frictionless trade with the EU impossible.
If no trade agreement is reached, the UK still faces the risk of a cliff-edge Brexit in 2021 when an 11-month status quote transition ends.
Earlier, Irish Prime Minister Leo Varadkar said that the EU would have the upper hand in trade talks, having the “stronger team” due to its larger population and market. Ireland, which is not a part of the UK, will remain a member of the bloc, while Northern Ireland, Wales and Scotland will exit along with Britain.
