Where to from here for Liberals and those on the centre left of British politics?

My starting point is my posting of 24th May 2014:-

The centre left of politics in England put up two blokes whom the electorate thought were not credible – Miliband and Clegg. Both should have gone a year or more ago. The Lib Dems and Labour Party will regret that they said it would be alright on the night; it was not!

More thoughts when I have had some sleep!!!!
