UK's glum Conservatives try to shift the mood with a promise of tax cuts as polling day nears

British Prime Minister Rishi Sunak has urged voters to throw him a lifeline in the U.K.'s July 4 election, promising to cut taxes if his Conservative Party is reelected. The party's election manifesto includes a pledge to slash a key tax paid by employees on their earnings. The launch came a day after Sunak was forced to deny rumors he could quit before next month’s election. Sunak acknowledged that “people are frustrated with our party and frustrated with me.” With three weeks to go, polls give Labour a significant lead over Sunak’s Conservatives.
