[Lemon flavoured]

Another one, going to 2015 this time. Thatcher stays in power in '90, but loses the '92 election:

Margaret Thatcher (Conservative) 1979 - 1992
Neil Kinnock (Labour) 1992 - 1997
John Major (Conservative minority) 1997 - 1998*
John Smith (Labour - LD coalition) 1998 - 1999**
Tony Blair (Labour - LD coalition) 1999 - 2003
William Hague (Conservative) 2003 - 2008
Harriet Harman (Labour minority) 2008 - 2010*
Simon Hughes (SDP - Labour - Liberal coalition) 2010 - 2012^
Jo Swinson (SDP - Labour - Liberal coalition) 2012 - 2015

* Removed by vote of no-confidence
** Died in office
^ Resigned as SDP leader and PM due to a sex scandal

Ok, a bit of SDP-wank at the end there, which needs explaining. Basically the Lib Dems fall apart after the 2003 election and Labour lose a lot of support after the vote of no-confidence in Harman's government.
