As Theresa May set her sights on the future, outgoing British Prime Minister David Cameron took the time to examine his past on his last moments in office.
It came after she swiftly appointed key cabinet members soon after taking office Wednesday, including new Treasury chief Philip Hammond and Boris Johnson, the former London mayor, as foreign secretary.
May replaced David Cameron after he stood down following the seismic June 23 vote to leave the European Union, which sparked three weeks of intense political turmoil and volatility on the financial markets.
In his farewell statement outside Downing Street, Mr Cameron said Mrs May would provide "strong and stable leadership" and wished her well in her negotiations on Britain's exit from the EU.
In an apparent attempt at a clean break, May ditched finance minister George Osborne, Cameron's closest ally.
She also stressed that the full name of the Conservative party was the Conservative and Unionist party, and she would safeguard the union between England, Scotland, Wales and Northern Ireland - as Scotland threatens to break away after the vote to leave the EU.
Gesturing across the room and up to his wife, Samantha, watching from the gallery, he said: "I will miss the roar of the crowd, I will miss the barbs from the opposition, but I will be willing you on".
May kept Michael Fallon as defence minister, while Amber Rudd was promoted to May's old interior minister job at the Home Office.
Eurosceptic former ministers David Davis and Liam Fox were appointed respectively as Brexit negotiator and minister for global trade, two new posts reflecting changed priorities after the referendum.
The United States congratulated May and said it is confident in her ability to lead Britain through the Brexit negotiations.
The blond, Latin-speaking Johnson - a leader of the campaign for a British exit, or Brexit - had aspired to be prime minister himself before his bid failed because of party infighting.
May had a phone call late Wednesday with German Chancellor Angela Merkel, who invited her to visit, followed by calls with the French and Irish leaders, a Downing Street spokeswoman said.
May is something of an unknown quantity internationally, but European Council president Donald Tusk said he looked forward to a "fruitful working relationship".
But she said Britain would "rise to the challenge" and forge "a bold new positive role" in the world.
Hammond said Thursday that there will be no emergency budget to deal with the economic fallout from Brexit.
She arrived at her new Downing Street residence with a promise to tackle "burning injustice".
Theresa has been home secretary for the last 6 years - she's the longest serving politician in the role for more than 50 years.
Mrs May has vowed to lead a "one nation" government that works for all not just the "privileged few".
A majority in Scotland voted for Britain to remain in the EU.
Its embattled leader Jeremy Corbyn urged May to "abandon the destructive austerity policies which have damaged our economy and undermined living standards".
