Doctor Who - History of the British Republic?

[ffutures]

Do we have any idea when and how Britain became a republic in the timeline that's now home to Rose Tyler and family, where Harriet Jones is President?

I've a vague idea for a story but it needs the change to have happened in the late 1930s or early 1940s.

Thanks. That's a possibility, but I really need there to be aristocracy up to the 1930s or so - it's a Lord Peter Wimsey crossover - so I think I'll be looking at the later possibilities first.
