sdp should have stayed in Labour and corrected what they didn't like...the runaway politician is one thats even less trustworthy than the norm..these that have left to join UKIP are same ilk..no backbone for a fight...so no good as politicians..because fighting for what you believe in should be their mantra.
I'm surprised that Clive didn't invoke a one time liberal politician who defected to the conservatives and ultimately became Prime Minister for the first time in 1940
