Theresa May is the new prime minister of the UK. She vows to build a country that “works for everyone,” after David Cameron formally stepped down. The leadership change all came just three-weeks after the UK voted to leave the European Union.

May arrived at Buckingham Palace for the Queen’s endorsement of her new role seated in a German car, a message that will not be lost on Berlin in future trade talks with the European Union.

But, as she swept into Downing Street, it was in the back of the Prime Minister’s official British-made Jaguar, the second woman in British history, after Margaret Thatcher, to take the top job.

Her first words as the country’s new leader, a message of social justice. But it was Brexit and the government’s failed referendum campaign that brought her to this place and will dominate her time in Downing Street.

May said, “Following the referendum, we face a time of great national change and I know because we’re Great Britain that we will rise to the challenge. As we leave the European Union, we will forge a bold new positive role for ourselves in the world.”

It was a journey outgoing Prime Minister David Cameron had made more than 300 times, but his last trip to Parliament for a final Prime Minister’s Questions was special.

Usually a barbed encounter holding government to account, this was knockabout stuff, complete with memorable moments from six years in power.

Cameron said, “When I met Mayor Bloomberg in New York and we walked down the street and everyone knew Mike Bloomberg and everyone came up said, ‘Mayor you’re doing a great job. Nobody had a clue who I was ’til eventually someone said ‘Hey, Cameron, Prime Minister’s questions, we love your show.’”

And for that he received a rare standing ovation from a jury of his peers. Only weeks ago, Prime Minister May had not thought she would be Prime Minister, until the government lost its Brexit referendum campaign and she proved to be the last one standing.

While we only have an outline idea of the style of government May will have, we do know one thing: that all the governmental issues of the day for the next couple of years will be dominated by Brexit.
