Kemi Badenoch, British Nigerian, on Saturday won the election to replace Rishi Sunak as leader of the Conservative Party.
The BBC reported that Badenoch, 44, beat Robert Jenrick after a four-month contest, sparked by Sunak’s resignation in the wake of a humiliating election defeat.
She is the first person of African heritage to lead the Tories.
The vote saw a turnout of 72% according to Conservative MP, Bob Blackman.
Most people said they had not formed an opinion of Ms Badenoch yet, according to a YouGov poll.
But 40 per cent of those questioned said they disliked her.
Former justice secretary Robert Buckland said that as a leader Ms Badenoch “will be an excellent person to work with”, having seen her strong character and abilities first-hand when they worked in government together.
“She knows that the party’s values need to be reset and that we’ve got to win trust as without trust, we don’t get anywhere in terms of electoral success,” he added.
“I think she better understands that more than most and that’s why she deserved to win.”
The role as opposition leader was an “unenviable task” and Ms Badenoch “will not be under any doubt about the scale of work ahead to win back power”, he added.
“She is the person who had more MP support than any other in the leadership race so people need to knuckle down and get on with the job of opposing the government, not opposing each other.”
He added that he hoped a “new phase in politics” would see Ms Badenoch unite the party and “the Tories regrouping”.
He also suggested that she listens to think tanks and policy units who have the expertise to provide her with new and innovative policies.
“It’s going to be very hard and unglamorous, but I believe Kemi has the strength of spirit to do it,” he said
