Esther McVey was appointed secretary of state for work and pensions as part of a reshuffle by Prime Minister Theresa May.
The U.K. government said Ms. McVey was appointed Monday. She was treasurer of HM Household, deputy chief whip, prior to the role.
The secretary of state for work and pensions has overall responsibility for the Department of Work and Pensions, with direct responsibility for departmental expenditure and management. The DWP administers the state pension and working age benefits system.
The role was previously held by David Gauke, who was appointed lord chancellor and secretary of state for justice, also on Monday. He held the pensions role since June 2017.
Ms. McVey is the fourth person to hold the job since 2016.
