So is he in every episode? I don't know the format
The format is like bake off, they make something every week, the worst one goes home. So, presumably if they have pulled the entire show, he is in enough episodes to warrant it.
They've suspended the series to investigate if the white supremacist tattoos are white supremacist tattoos. When they realise that they are I guess then they will evaluate if they can show any of the remaining series. If he's eliminated in one of the first few episodes I'm sure they could do some sort of recap for episodes skipped over and carry on from the episode after he's left. Although I read that the judges were impressed by his 'heart-shaped stool' in the first episode so it could be that he ends up wining the whole thing.
Found the tweet, his dad was on the electoral roll at least as recently as 2011 and had been living in that address since 2002, so no way he died in 1988:
Sky claim to have done extensive research, that didn’t include looking at his face, but very basic research throws up the fact that his father was on the electoral roll at a Bristol address from 2002-11 despite allegedly dying in 1988. https://t.co/QM77aXJp0M
It was the doubling down 'this is fine' by the press office/social team that amazed me. I know there's a lot of Twitter witch-hunts but enough people were flagging sensible concerns. Presumably some very senior people were then roped into the conversation yesterday which led to the entirely predictable outcome.
Whether the series can be salvaged remains to to seen. If he was out after a couple of weeks then shouldn't be too difficult. If he won...then no chance. Anything in-between may require some awkward editing (I've not seen it but if it's like Bake Off then things like the shot of them all lined up being judged etc.)
