Keir Starmer: who is Britain’s likely next prime minister?

Britain's Labour Party is the favourite to win the country's July 4 general election, which would see its leader, Keir Starmer, become prime minister.

Starmer has transformed the party since he took over in hopes of bringing Labour back into power after 14 years in opposition.

But his journey from a left-wing human rights lawyer to a centrist pragmatist has left some wondering who he really is, and what his party will do in government if elected.
