Britain's Yvette Cooper was named foreign minister on Friday, replacing David Lammy who will become deputy prime minister and justice minister, Prime Minister Keir Starmer's office said in a statement.
The appointment is the most significant of a cabinet reshuffle carried out by Starmer following the resignation of deputy prime minister, Angela Rayner, after she admitted underpaying property tax on a new home.
Shabana Mahmood, currently the justice minister, will replace Cooper at the home office - or interior ministry - taking on the brief which includes tackling illegal migration.
The government also appointed new ministers in departments including the environment, business, housing, and work and pensions.
