Jon Trickett MP, Labour's Shadow Minister for the Cabinet Office, responding to reports about Lord Fink, said:
"This is a flagrant attempt to breach the rules of Parliament. It leaves a very nasty taste to suggest that you can buy access to the House of Lords, and it cheapens democracy.
"Lord Fink, who is a major donor to the Tories should consider his position as Treasurer of the Conservative Party and if he refuses to do so the Prime Minister should sack him.
"To have one Tory Treasurer in trouble for appearing to sell access to Number 10 is bad enough, some might think that now to have a second Treasurer apparently in breach of the code of conduct is a sign of systemic moral failure in the high command of the Conservative Party."
