Former Prime Minister Theresa May was given a standing ovation by British MPs after her last, at times emotional, appearance in parliament.
May, 62, appeared to be barely holding back tears as she stopped to shake hands with the Speaker of the House of Commons, John Bercow, on her way out.
He will later officially hand over the position to his successor, Boris Johnson.
"Later today I will be back in the Commons and it will be the first time in 21 years, which will be a really big change," May told MPs at the end of her final Sunday session in Parliament.
As she praised the bond between MPs and their constituents, calling it "the foundation of our parliamentary democracy", her voice trembled and she added: "The duty to serve our constituents will continue to be my greatest motivation".
She also called on Corbin to resign
During the parliamentary session, the former prime minister gave the last blow to the leader of the opposition, Jeremy Corbyn, when she suggested that he, like her, resign from office, reports Hina.
"I think she could end her relationship with him with this - as a party leader who has accepted that her time is up, maybe now is the time for him to do the same," May said, drawing loud applause from her Conservative MPs and chants of "more".
During the one-hour session, which her husband Philip watched from the gallery, all political parties paid tribute to the former prime minister for her public activity and sense of duty, despite clearly expressing disagreement with many of her decisions.
Television footage from a press helicopter overhead showed parliamentary staff lining up in the courtyard, applauding and taking photos of the event, as the outgoing Prime Minister walked to her car for her final return to her Downing Street office.
He will officially submit his resignation to the Queen
It is expected that he will give a short speech there before going to Queen Elizabeth to whom he will officially resign and nominate Johnson as the mandate to form a new government.
May assumed the position of Prime Minister after the 2016 referendum in which it was voted to leave the European Union, and she is resigning just over three years after she failed to implement Brexit, and her exit agreement with the European Union was rejected three times in a deeply divided parliament.
British Chancellor of the Exchequer Philip Hammond also resigned on Wednesday after previously promising to leave rather than serve in Prime Minister Boris Johnson's government.
Hammond, who is fiercely opposed to leaving the European Union without a deal, said he had left the economy in a state that would allow his successor to decide between tax cuts, higher spending or faster debt reduction if they leave the EU without problems.
"After a decade where we had no choice because of the recession of 2008 and 2009, this is now a luxury that our successors should use wisely," Hammond said.
