The front-runner for the U.K. prime minister role, Andy Burnham, in his speech on Monday showed commitment to fiscal measures, calming investor concerns about possible shift to looser rules, Barclays Jack Meaning and Cian Hennigan say in a note. "There was no sense of trying to find ways to game the rules or increase borrowing, which would have worried markets," the economists say in a note. Ten-year gilt yields fall to last trade at 4.728% following the speech, from 4.745% beforehand, Tradeweb data show. (miriam.mukuru@wsj.com)
