Keir Starmer Pledges To Rebuild UK 'Brick By Brick' In First Speech As Prime Minister. British Prime Minister Keir Starmer said he would lead a “government of service” on a mission of national renewal in his first official remarks Friday after his Labour Party swept to power in a landslide victory after more than a decade in opposition. Starmer acknowledged in his first speech outside 10 Downing St. that many people are disillusioned and cynical about politics, but said his government would try to restore faith in government.
