Liz Truss is officially taking the reins of power today - and there is unlikely to be a honeymoon period.
One of the most pressing issues the new Prime Minister faces is how to tackle the cost-of-living crisis.
The Telegraph can disclose that Ms Truss is considering plans to freeze energy bills until 2024, when the next general election is expected.
As she replaces Boris Johnson in Downing Street today, Ms Truss will give a speech to outline her vision for her premiership as well as setting out her agenda for her first 100 days.
A package of support on energy bills is due to be revealed as early as Thursday, followed within weeks by a formal announcement of tax cuts and a plan to clear the NHS backlog.
Political editor Ben Riley-Smith explains how her approach to energy bills could be a "huge" policy intervention.
In this bonus episode of our Chopper's Politics podcast, Christopher Hope is joined by Camilla Tominey and Gordon Rayner to unpack the next moves for the incoming PM.
At 7.30am, Mr Johnson brought his three years in office to an end with a speech in Downing Street. He said: "This is it, folks," as he described himself as a "booster rocket".
Mr Johnson - who is reportedly preparing to move into a borrowed house, where he could finish a memoir of his time in Downing Street by Christmas - will later this morning visit the Queen at Balmoral to step down.
Ms Truss will follow him in to become the country's third female prime minister, before flying back to London and delivering her speech to the nation at around 4pm.
Follow all the action with our politics live blog editor Jack Maidment. And this is an hour-by-hour guide to Ms Truss's first days as Tory leader.
The new Cabinet is expected to be unveiled this evening, with half a dozen of Ms Truss's most loyal supporters, largely on the party's Right, expected to be given the most senior roles.
Many of the biggest jobs are understood to have been decided, with none of the four great offices of state set to be occupied by a white man. Read who we understand will be in the most diverse top team ever.
Some roles are still under discussion. Thérèse Coffey, a close friend of the Foreign Secretary, is tipped to become deputy prime minister and health secretary - a move Camilla Tominey says could make her the lynchpin of the team.
However, allies of Penny Mordaunt are pushing for her to be promoted to the deputy role to unite the Tory party. Meanwhile, it is understood that Lord Frost, the former Brexit negotiator, has turned down two Cabinet roles.
When Ms Truss was announced as the leader of the Conservative Party yesterday, the nation got a rare glimpse of her husband, Hugh O'Leary.
The 48-year-old made no public appearance on the campaign trail, with Ms Truss telling The Telegraph that "he doesn't want to have a sort of massive public role".
She described her accountant husband as a "very stoic person" who is supportive of her career.
Rosa Silverman and Helen Chandler-Wilde explain everything we know about Mr O'Leary.

Meghan's speech | The Duchess of Sussex has revealed she did not feel like she "belonged" among leaders and humanitarians when she first started advocating for a better world, as she was just "the girl from Suits".
