The treasurer of the Conservative Party is facing Labour calls to quit after he agreed to host a House of Lords dinner as part of a £6,000 entertainment package for American Express cardholders.
Lord Fink, a major Tory donor and David Cameron's chief fundraiser, was accused of breaching parliamentary rules by sponsoring the private dinner. It was part of a $9,391-a-head (£6,000) Wimbledon Championships package available to AmEx Platinum and Centurion card-holders.
The Tories said Lord Fink was no longer sponsoring the dinner after it was brought to his attention that it may be in breach of the rules.
He was appointed in March after Peter Cruddas resigned.
