"Any political party is a coalition of sorts - we Conservatives certainly have plenty of tribes of our own, who disagree about plenty of issues. But Lib Demmery is a more divided creed than most.
Having been formed from a merger of two parties, it has never succeeded in bringing the left and centre any closer together. The rift extends to the social level as well as just the ideological - you don't see many deficit hawks hanging out over beers with the Keynesian wing of the party."
I didn't expect their conference in Glasgow to provide a more vivid demonstration of this than the economy debate, but an anonymous MP on the Liberal side of the divide has helpfully provided a confirmatory quote to The Sun's Tom Newton Dunn:
“We should boot out Vince Cable from the party. Him, and all the SDP lot. The merger hasn't worked."
Any party has its disagreements, but this of a different order - and it isn't going away.
