U.K. Prime Minister Theresa May survived a vote of confidence in her leadership of her party Wednesday, but not until after a bruising challenge in which she reportedly promised she would step down before the next general election.

A leadership vote had been triggered after 48 Conservative Party MPs had written letters expressing no confidence in her leadership -- 15 percent of the party's members in the Commons.

But the vote of confidence of the broader bloc of Tory MPs went in her favor -- with 200 MPs backing her leadership and 117 voting against her.

Tom Harwood, reporter for Guido Fawkes and a member of the Parliamentary Press Lobby in the UK Parliament, joined Fox News Radio's Guy Benson and Marie Harf to discuss the vote of no-confidence. 

On an explanation of the vote of no-confidence: It's a bit confusing because you can have a vote of no confidence in a government and that would lead to the government to collapse and fresh elections be called. However, this was an internal party vote of no-confidence with regard to the leader of the Conservative Party.  This was an internal party matter that was brought about because 48 conservative members of Parliament wrote a letter to the chairman of their party in Parliament and that is enough to trigger this balance where if the Prime Minister were to lose she would be removed as leader of the conservative party and there would be internal party elections for a new leader of the Conservative Party and therefore a new Prime Minister. (1:53) 

On expectations before the vote: From this morning people felt that this could have been a winnable vote. Right when it was called West Minster was incredibly excited. The atmosphere was electric. Then there was Prime Minister's questions right in the middle of the day at 12 o'clock and this is the weekly sparring match between the leader of the Conservative Party, the Prime Minister, and the leader of the opposition. The Prime Minister answers questions. It's a big debate televised every week. Theresa May was seemed to have done quite well in today's prime minister's questions and she really got back on her feet. From that point onward, the general atmosphere was that she was going to win. (3:02)

On if there is a solution to make everyone happy: The country was divided 52% to 48% in the referendum on Brexit, which means that a significant minority of people are not going to be best pleased. I think the problem here is Theresa May of course didn't vote for Brexit. She voted against Brexit in that referendum and the majority of the Conservative Party did... What you have had over the last two years is a Prime Minister who is trying to deliver a policy that she never believed in or fought for. (4:56)
