People switched their votes from Labour to the Lib Dems and woke up with a Tory MP in some cases. Red face day for them methinks.

I'm not so sure about that. In my area, last time the voting was marginal, with Lab and Con both around the 15000 mark, with Labour ahead by about 1500, and with Lib Dem around 4000. Plenty of people I know voted for Lib Dem fully aware that the only likely outcome was that the Conservatives would win. However, they wished to see a much smaller majority for Labour and recognised that having a Conservative in their area was the price to be paid. Having decided that, the only choice was a direct or indirect vote for the Conservatives. Roughly speaking, those who were 'old Labour' found voting for Conservative impossible and so voted Lib Dem well aware of the consequences.
