Yes. If you win the party, typically the party will arrange for a seat be made available and a bi-election held. But you don't have to.
You could wait until the next election. This has happened several times before and even fairly recently. Edit: Looking up an example, here is one better.
John Turner was elected leader of the Liberals in June 1984. (He had been an MP, but it was almost ten years before 1984) He became Prime Minister that same month. He wasn't MP until the election they lost in September 1984.
So he was party leader and Prime Minister without being a MP.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
