Therese Coffey, Member of Parliament, was named the U.K. Secretary of State for Work and Pensions, following the Sept. 7 departure of Amber Rudd.
Ms. Coffey oversees the Department for Work and Pensions, which is responsible for drafting U.K. pension regulations, and the administration of the state pension and working age benefits system. Ms. Rudd left Prime Minister Boris Johnson's cabinet over disagreement with Mr. Johnson's decision to expel 21 Tory party members of Parliament, following their refusal to follow his orders in a vote on his Brexit strategy last week.
Ms. Rudd accused Mr. Johnson of "political vandalism" and said he is not trying hard enough to secure a Brexit deal with the European Union.
Ms. Coffey was previously minister of state at the Department for Environment, Food and Rural Affairs from July 25 to Sept. 8.
Ms. Coffey is a graduate of University College London.
