Theresa May - timeline of her first 100 days at the helm


Here is a timeline of the key moments in Theresa May's premiership:

:: July 13

Theresa May arrives at Buckingham Palace and is invited to form a government by the Queen. As the new PM arrives in Downing Street she promises to tackle injustice, saying ''the Government I lead will be driven not by the interests of the privileged few''. Just over an hour later, Mrs May begins appointing her new Cabinet, making Philip Hammond Chancellor of the Exchequer. In a surprise move, leading Brexit campaigner Boris Johnson is appointed Foreign Secretary. George Osborne is kicked out of the Government. David Davis is made Secretary of State for Brexit and Liam Fox becomes International Trade Secretary.

:: July 14 

The new Prime Minister continues to make appointments to her top team but also clears out a number of senior figures from David Cameron's era in a wave of sackings. Justice Secretary Michael Gove is sent to the backbenches along with Oliver Letwin, Nicky Morgan and John Whittingdale.

:: July 15 

Mrs May uses her first official visit as Prime Minister to try to persuade Scotland that there is nothing to fear in a post-Brexit UK. The premier heads to Edinburgh for talks with SNP First Minister Nicola Sturgeon and tells Scots she believes ''with all my heart'' in keeping the UK together.

:: July 20

Mrs May mocks Jeremy Corbyn as an ''unscrupulous boss'' who exploits Labour Party rules to further his own career as they clash for the first time at Prime Minister's Questions. The PM then jets off to Berlin for her first overseas visit since becoming premier and is given a full ceremonial welcome as she meets Angela Merkel.

:: July 21

The Prime Minister heads to Paris for talks with French president Francois Hollande, who warns that Britain will not remain in the Single Market unless it accepts freedom of movement.

:: July 29 

The Government pulls back from signing a deal to build the first new nuclear power station in the UK for a generation because Mrs May wants a fresh look at the evidence for the £18 billion plant.

:: August 12

Mrs May heads out on an Alpine trek with husband Philip as they began a two-week holiday in Switzerland.

:: September 4

 Mrs May attends her first international summit when she flies to China for the G20. The PM rules out the points-based immigration policy championed by Brexit campaigners, saying it is ''not a silver bullet'' to reduce the numbers coming to the UK.

:: September 9 

In her first domestic speech since becoming PM, Mrs May sets out plans for a new wave of grammar schools to end ''selection by house price'' and give every child the chance to go to a good school. It comes days after a document proposing the controversial plan for new grammars was photographed outside No 10.

:: September 20 

Mrs May makes her first speech to the United Nations General Assembly, insisting the UK did not "vote to turn inwards" when it backed Brexit.

:: October 2

As she makes her first speech to the Conservative conference as party leader, Mrs May announces Britain will trigger Article 50 of the Lisbon Treaty to begin the formal process of leaving the European Union by the end of March 2017. The announcement spooks the markets and the following day the pound slumps. The PMs also set out plans for a Great Repeal Bill that will enshrine all European Union regulations that apply to Britain in domestic law when the country leaves the bloc.

:: October 5

Mrs May vows that ''a change is going to come'' as she promises to take the Conservatives onto the centre ground in her keynote Tory conference speech. The Prime Minister says she is determined to make Britain a ''great meritocracy'' based on the values of ''fairness and opportunity''.

:: October 20

The PM arrives in Brussels for her first European Council summit.
