This is a list of resignation statements from the Liberal Democrats. It includes people who seem to be liberals, it doesn't include those who have defected to Labour (why would a liberal do that?) or the Tories (?!), or resignations which seem to centre on local or personal circumstances. It does include a couple of Greens.
This is bound to be incomplete, please let me know if you have other suggestions for inclusion.
The intention is that this will give some cumulative sense of why liberals have left the party:
