Sajid Javid has been named as the new home secretary after Amber Rudd’s resignation.
Mr Javid, the son of a Pakistani bus driver whose family came to the UK in the 1960s, is currently Communities, Local Government and Housing Secretary.
Before that, the former investment banker and MP for Bromsgrove had been Business and Culture Secretaries.
Ms Rudd quit saying she had “inadvertently misled” MPs over what she knew about immigration targets.
Her exit followed weeks of revelations about the treatment of Windrush families, who settled legally in post-war Britain but whose right-to-remain has been questioned, and controversy over the government’s “hostile environment” immigration policy.
Following Mr Javid’s promotion, No 10 also announced that former Northern Ireland Secretary James Brokenshire will return to the cabinet as Housing, Communities and Local Government Secretary.
The 48-year-old Mr Javid, who first entered Parliament in 2010 and supported remaining in the EU despite being regarded as a Eurosceptic, led the government’s response to last year’s Grenfell fire disaster.
Over the weekend, he told the Sunday Telegraph the Windrush scandal felt “very personal” to him as coming from a family of immigrants “it could have been Mum, Dad or me”.
