Did Ming fall on his sword or was he knifed?

With the Lib Dems reeling from their dreadful local election results in May and trailing in the polls on 11% it was inevitable that Sir Ming Campbell would go. I am suprised at just how quickly it has happened.

There were signs of obvious Lib Dem discontent, with Simon Hughes showing typical veiled disloyalty over the weekend, suggesting that Ming could "do better", and Vince Cable saying his position was "under discussion".

The two questions now being asked are 1) who wielded the knife and 2) who will be the new leader - the two front runners must be Nick Clegg or Eastleigh MP Chris Huhne.
