In page David Cameron:

"

On 4 April 2000, Cameron was selected as PPC for Witney in Oxfordshire. This had been a safe Conservative seat, but its sitting MP Shaun Woodward (who had worked with Cameron on the 1992 election campaign) had "crossed the floor" to join the Labour Party and was selected instead for the safe Labour seat of St Helens South. Cameron's biographers Francis Elliott and James Hanning describe the two men as being "on fairly friendly terms".[12] Cameron, advised in his strategy by friend Catherine Fall, put a great deal of effort into "nursing" his potential constituency, turning up at social functions, and attacking Woodward for changing his mind on fox hunting to support a ban.[13]
