Sterling rises slightly after Andy Burnham, the frontrunner to succeed Prime Minister Keir Starmer, vowed to boost growth across the U.K while reaffirming his commitment to meeting the fiscal rules. Burnham said his plans to improve growth and raise living standards will be backed by "sound" public finances. Burnham is widely expected to become prime minister after Starmer announced his resignation last week. Sterling rises 0.2% to an intraday high of $1.3230 after the speech from $1.3209 beforehand. The euro falls 0.1% to 0.8618 pounds from 0.8629 pounds. (renae.dyer@wsj.com)
