Lib Dem conference: Cable and Alexander poll on economy
Liberal Democrats have been polled on their favourite number-crunchers, with the choice of self-proclaimed Jeremiah of Twickenham Vince Cable, or the member of the powerful "quad" group of ministers, Danny Alexander.
The Daily Politics mood box - an unscientific test of plastic bins with balls - saw delegates at the party conference asked to choose between the business secretary and the chief secretary to the Treasury.
