They've then got a number of what are sometimes called top-up seats on top of that.

So you get a second vote for your region.

So, for instance, Glasgow is one of the regions.

And what that is designed to do is designed to sort of iron out some of the quirks of first-past-the-post, where one party can win lots of seats on a relatively small share of the vote.

It compensates parties who've missed out on those seats.

So...

Two electoral systems sort of working in one to produce this kind of semi-proportional system.

And James, you actually see that some of the parties have been quite explicit when they're talking to their potential voters saying, oh, vote for us on this ballot paper because this is where we will do better.

Yes, so particularly some of the smaller parties stressing the importance of that second vote because they know they're unlikely to win in a constituency.

And so they are trying to encourage you to vote for them on the second vote in the regional list, as it's called.

And it's called a list because the parties decide, they submit a list of candidates and you vote for the party and then...

They go to that list.

And if you get enough, you get the first person on your list.

And if you, after a lot of complicated calculations, get enough for another seat on the list, you get the second person on the list and so on.

So being at the top of that list is really important if you want to be a prospective.

Well, if you want to be an actual, you can be a prospective one if you want to be an actual member of the Scottish Parliament.

James, yeah, so that's the science bit.

You've been doing lots of the news bit this week.

For example, on Sunday night, I saw on the 10 o'clock news, a lovely lineup of Rita wearing a big coat, you're wearing a natty scarf and Chris Mason, as usual, not wearing any weather appropriate clothing.

You stood outside a building in Paisley to the west of Glasgow because it had been the BBC leaders debate.
