Prime Minister Andy Burnham will face lawmakers in the House of Commons on Tuesday for the first time since becoming U.K. leader six weeks ago, with wars in Europe and the Middle East weighing on his promise to kick-start the economy and ease the cost of living.

Since taking office on July 20, Burnham has traveled around the country promising to deliver renewed national optimism after the downbeat two-year tenure of predecessor Keir Starmer, who announced Tuesday that he would resign his seat in Parliament after 11 years.

Burnham has announced a series of modest money-saving measures aimed at giving "breathing space" to people and businesses, including a tax cut on domestic energy bills and a lowering of levies on pubs and nightclubs.
