Sajid Javid has been appointed as the new Home Secretary after Amber Rudd quit last night.
He will be replaced as Communities and Local Government Secretary by James Brokenshire.
It comes after Ms Rudd apologised for telling MPs she didn’t know about Home Office targets for deportations in the wake of the Windrush ‘scandal’.
Her resignation letter said she ‘inadvertently misled’ parliament.
International Development Secretary Penny Mordaunt will also take on Ms Rudd’s former responsibilities as Minister for Women and Equalities, Downing Street announced.
It follows intense pressure for Ms Rudd to step down over the Windrush generation crisis, which saw people who came to the UK as citizens detained in immigration centres, denied healthcare and threatened with deportation.
The Hastings and Rye MP became the fifth minister to leave the Cabinet since last year’s snap general election.
Her resignation letter said she took ‘full responsibility’ for not being aware of the existence of targets.
Mrs May said she was ‘very sorry’ to see her successor as home secretary leave the post, while Ms Rudd’s opposite number Diane Abbott said she had ‘done the right thing’.
The pressure had been building on the former banker ever since the emergence of the ‘appalling’ treatment of Caribbean immigrants to the UK between the 1940s and 1970s – the so-called Windrush generation.
Concerns had been raised about the immigration status of the Windrush generation and there had been stories of people being forced to prove their annual presence in the country for decades in order to prove they were here legally.
Ms Rudd referred to the Windrush ‘scandal’ in her two-page resignation letter, admitting that people with a right to live in the UK had not always been treated ‘fairly and and humanely’.
Opposition parties said she was paying the price for Mrs May’s ‘hostile environment’ policy towards illegal immigrants when she was Home Secretary which had led to people being wrongly stripped of their rights and threatened with deportation.
