Liberals leaving a sinking ship

Whilst looking at recent local election results came across this interesting set of statistics.

Since the May 2011 local elections there have been 28 instances where councillors have defected from one party to another:

Labour have had 9 councilors Join them from other political parties and had one member defect to another group.

The Tories, have lost 3 to defections but gained seven from other groups, but it is no surprise to us involved in local politics that it is the Lib Dems who have seen the most defections since May. they have gained one councillor from another political group but have had 16 of their councillors leave for other groups.

Liberals leaving a sinking ship?

Have edited this post after a Lib Dem complained- I was just using a common English term used when anyone flees what has become a lost cause . Apologies for any offence caused.
