AHC: A Century of Scottish UK Prime Ministers

Well Prime Ministers of Scottish origin are already surprisingly common over this time period, given Scotland's relative population within the UK. Off the top of my head you've got MacDonald, Macmillan, Home, and Brown. Blair and Cameron could probably be included with a minimal bit of alt history, given their family background.

Anyway, for the challenge:

Andrew Bonar Law* (1915-1922) National
George Younger (1922-1929) National
Sir Archibald Sinclair (1929-1933) National
Patrick Boyle, Lord Glasgow (1933) National

Arthur Henderson (1933-1935) Labour
Peter Fraser (1935-1949) Labour
Manny Shinwell (1949) Labour
Valentine Fleming (1949-1960) Conservative
Sir John Gilmour (1960-1965) Conservative

Jennie Lee (1965-1972) Labour
Teddy Taylor (1972-1977) Conservative
Dick Mabon (1977-1987) Labour
Malcolm Rifkind (1987-1992) Conservative
Donald Dewar (1992-2000) Labour
Jim Dobbin (2000-2001) Labour

Liam Fox (2001-2011) Conservative
Yvette Cooper (2011- ) Labour

There's a vague timeline for parts of this, it being my usual mix of obscure OTL figures, foreign parallels, and "interesting" characters. I can't say stands up much in plausibility terms. Then again, at some point during this Caledonian Century someone would probably stand up and say "Hang on a minute, there's a pattern here..."

Could be more interesting if they all end up representing English or Welsh constituencies (as many of them in fact did in OTL). Tedious Technicaly True Fact: there are now more Labour MPs of Scottish origin in the West Midlands than there are in Scotland.

*Half-cheating to anchor the list to OTL 1915, plus he basically grew up in Scotland anyway.
