From David Cameron's whistle to Theresa May's tears: How Prime Ministers' historic first and final Downing Street speeches compare

Margaret Thatcher, dubbed 'The Iron Lady', became Britain's first female MP in May 1979 having beaten former Tory PM Edward Heath to become party leader in 1975. When Thatcher arrived at Downing Street after winning, she was beaming

Thatcher, who studied chemistry at the University of Oxford, was first elected as an MP for Finchley in 1959, holding junior posts before becoming Shadow Spokesperson for Education, and entered the Cabinet as Education Secretary in 1970. Here she is celebrating getting the top job as PM

She entered Number 10 first the first time, where a large group of press and photographers from across the globe was waiting. Becoming a PM during the Cold War, Thatcher would famously order the British military to retake the Falkland Islands after Argentina invaded in 1982. The following year, the Conservatives went on to win the 1983 election by an overwhelming majority

But by 1990, the glitter of her time as PM was over. Thatcher had introduced a radical programme of privatisation and deregulation and reform of the trade unions following the Winter of Discontent.  Things came to a head in November when her long-serving Foreign Secretary  Sir Geoffrey Howe resigned in protest at her attitude to Europe. His resignation speech brought about events which were to lead to her exit from Number 10 later that month. Baroness Thatcher died on April 8 2013

John Major became the next Prime Minister and leader of the Conservative Party, and attempted to make peace between both party and country in the wake of a divisive decade. He took a leading role, alongside US President George HW Bush, in the first Gulf War, and survived an IRA mortar attack on Number 10 during a Cabinet meeting

But Major - who before becoming PM had a four-year affair with his Tory colleague Edwina Currie - finally resigned in May 1997. Despite having been elected in 1992, his government was plagued by press stories about infidelity and poor moral behaviour within the Cabinet and wider party - with the label of 'Tory sleaze' sticking, effective wiping out his credibility. 

New Labour leader Tony Blair arrived to scenes of fanfare and jubilation when he clinched a landslide victory in the 1997 General Election - with D:Ream's anthem Things Can Only Get Better soundtracking his win.

At just 43, Blair was the youngster person to become Prime Minister since Lord Liverpool was PM at the age of 42 in 1812. And the Labour leader's opening trip into Downing Street saw him championed as a political rock star, with fans waving Union Flags as he arrived with his wife, Cherie (pictured)

On foreign affairs, Blair became increasingly convinced of Britain's need to become more involved, joining the American bombing of Iraq in 1998 - before later getting involved in the war in Kosovo

He entered Number 10 having waved to the crowds, with his wife and children leading the way into Downing Street

Just three months later, the 9/11 terrorist attacks in America rocked the world - and became the defining moment for for the Labour leader and his legacy. He allied with the USA and President Bush over the need to confront militant Islamism, first in Afghanistan in 2001 and then, much more controversially, in 2003 with the invasion of Iraq

2007: But just six years later, Blair gave his final speech outside Number 10 before being pictured with children Euan, Kathryn,  Leo, and Nicky and his wife Cherie. Blair's last years in office saw him criticised over his handling of the Iraq war, after it was revealed claims weapons of mass destruction were in the country were false. And in 2006 the Israel-Lebanon war saw a very large Labour rebellion against him over his reluctance to criticise Israel and his continued support for Bush. He resigned as PM on June 27

Gordon Brown first came to power following the resignation of his former boss in 2007. Prior to this he had been the Chancellor during the longest ever period of economic growth. He is pictured arriving in Downing Street with his wife Sarah

2007: Brown's time in charge saw him dealing with the global financial crash of 2008. And UK combat operations in Iraq, which had begun during his predecessor's time in office, came to an end under Brown. British forces withdrew from the country at the end of April 2009. Brown is pictured being driven into Downing Street in June, 2007

2010: Gordon Brown's time in Downing Street came to an end in May 2010. It came after a general election which left no one party with enough of a majority for form a government by themselves.

2010: Cameron's government also held three national referendums. The first in 2011, known as the alternative vote referendum, asked whether the current existing method of electing MPs should remain for future general elections. The second referendum held in 2014 asked whether Scotland should be an independent country

2016: However, it was the third referendum - Brexit - which proved to be his last act as PM. Having campaigned to stay in the EU, he lost the referendum to the Leave campaign, who netted 51 per cent of the vote. Cameron's failure to win the vote, prompted by leading Brexiteer Nigel Farage, prompted him to resign as Prime Minister. He is pictured giving his final speech

But she was dogged by division within parliament when it came to trying to get Brexit done

2019: Mrs May was left sobbing at the podium following an emotional farewell speech.  She quit after a tumultuous two years and 315 days in office - making her the 36th longest serving Prime Minister in British history. Watched by her husband Philip in Downing Street, Mrs May managed to keep her composure until the emotional moment she finished her 1,000-word speech, breaking down in tears. She ultimately left having failed to deliver Brexit

She quit as PM October 25, becoming Britain's shortest serving prime minister. She eventually lost her seat in Thursday's General Election

2022: Mr Sunak's opening speech featured none of the usual celebratory spirit, against the backdrop of a crippling cost of living crisis and the historically unsuccessful record of his predecessor

In his final speech in Downing Street. flanked by his wife Akshata, Mr Sunak apologised to voters, saying had 'heard the anger' of the country and the 'clear message' of the ballot
