Britain's main opposition Labour Party named Keir Starmer, a former director of public prosecutions who opposed the country's exit from the European Union, as its leader on Saturday.
Starmer, who has tried to carry the socialist supporters of outgoing leader Jeremy Corbyn while also keeping more centrist Labour members on board, beat Rebecca Long-Bailey, an ally of Corbyn, and Lisa Nandy in the contest.
He won with 56.2% of the vote by party members and supporters.
"It's the honour and privilege of my life to be elected as leader of the Labour Party. It comes at a moment like no other in our lifetime," he said in a pre-recorded statement, in reference to the ongoing coronavirus pandemic.
"Under my leadership, we will engage constructively with the government, not opposition for opposition's sake. Not scoring party political points or making impossible demands. But with the courage to support where that's the right thing to do."
"But we will test the arguments that are put forward. We will shine a torch on critical issues and where we see mistakes or faltering government or things not happening as quickly as they should, we'll challenge that and call that out."
The leadership contest, underway since Corbyn led Labour to a crushing defeat in the December election, has been overshadowed by the coronavirus outbreak, which all but silenced the three candidates' campaigns.
