The above four MPs are standing down from Westminster at the general election, but the three former Cabinet Ministers, Geoff Hoon, Patricia Hewitt and Stephen Byers were all caught on camera discussing 'job offers' from a bogus form set up for a sting operation by Channel 4.
A fourth Labour MP, Margaret Moran, is thought to have offered to 'influence legislation'.
Stephen Byers (£3,000 to £5,000 a day), the former Transport Secretary, admitted yesterday that he had exaggerated his political influence during his interview.
Geoff Hoon's solicitor said, on Friday, that his comments had been misrepresented and he denied over offering to give confidential information.
Aides to Gordon Brown say they are most concerned by Ms Moran's interview in the Dispatches programme in which she can be heard promising to help modify laws on immigration in order to boost the business interests of the fake company. One senior Labour source said that Ms Moran was 'not very well' and anything she said should 'not be taken seriously ... the idea that she has the ability to influence anything is laughable'.
The idea that any of these people is in a position to make laws for this country isn't laughable, it's downright tragic for all of us. Mind you, they were taught well by their ex-boss.
The Dispatches programme can be seen on Channel 4 tomorrow (Monday).
