To over simplify, it would be like the Speaker of the House being President here.
Sometimes there is pressure to call a snap general election if something like this happens, but votes in elections go towards electing MPs. The party with the largest amount of seats gets to choose the PM.
Andrea Leadsom stepped down as commons leader the other day, and was one of the candidates for PM the last time around, so I would expect she will be one of the favourites now.
We don't vote for the prime minister we vote for a political party, like your Republicans or Democrats.
Theresa May was not the elected prime minister, she took over when David Cameron (pig fucker) resigned.
She promptly called an early general election and lost the Conservative majority in the House of Commons. Instead of immediately resigning she has continued to astound with her denial and cack handedness.
Wow. I can't believe it. I wonder what this means for Brexit.
What I don't understand, though, is why her party has to decide a new Prime Minister. Why wouldn't it be a whole new election where someone from any party could win? This is something I don't understand about UK politics, there's probably a logical answer I'm not aware of.
