Finance proved a major problem for the Labour Party during this period; a "cash for peerages" scandal under Blair resulted in the drying up of many major sources of donations. Declining party membership, partially due to the reduction of activists' influence upon policy-making under the reforms of Neil Kinnock and Blair, also contributed to financial problems. Between January and March 2008, the Labour Party received just over 3 million in donations and were 17 million in debt; compared to the Conservatives' 6 million in donations and 12 million in debt.

Who increased the influence of activists?
