Recommendation for Documentary about voting in the UK

[Jellyshoeshurtmyfeet]

My DS 13 has been asked to watch a documentary about voting in the UK. It can be any documentary but I'm struggling to find anything that's not specifically about Brexit. Can anyone recommend one Please? TIA

Should have said it's homework!

I thought this should be fairly easy to find, but no. Even a Google search (which you have surely tried) doesn't come up with much.
Try this - there are more subjects on the sidebar to the left...

This site looked promising, but I couldn't find the documentary - could be just my browser...

That's fantastic, thanks so much for your help. Homework completed. I also thought it would be really easy to find something but it really wasn't . We used the 8 minute one.
