David Abrahams

Could be either:

David Martin Abrahams - The Labour Party donor

David Abrahams (lobbyist) - a lobbyist formerly at LLM Communications

There's also a David Abrahams - property developer who donated to the Labour Party (not sure if it's the same as David Martin Abrahams above). The Daily Mail reports...

'Police are already looking at proxy donations to Labour of more than £600,000 from property developer David Abrahams, which Mr Brown has said were 'unlawful' and not properly declared. That case has already claimed the resignation of Labour's general secretary, Peter Watt'.
