I am quite strict as a dad but I don't want to be censorious.

Liberalism is a really old British tradition and it has a completely different attitude towards the individual and the relationship between the individual and the state than the collectivist response of Labour, and particularly Old Labour, does.

On the BSkyB bid, Rupert Murdoch is now in town in London seeking to sort things out. I would simply say to him, look how people feel about this. Look how the country has reacted with revulsion to the revelations. So do the decent and sensible thing and reconsider, think again, about your bid for BSkyB.

Our Sheffield and London homes are worth well over a million but the bank owns most of them - we are mortgaged up to the gills.

I totally rule out any arrangements with the SNP — in the same way I rule out any arrangements with Ukip - because there is no meeting point for me with one party that basically wants to pull our country to bits and another party that wants us to pull out of the EU. I would never recommend to the Liberal Democrats that we help establish a government which is basically on a life support system, where Alex Salmond could pull the plug any time he wants.
