The Conservative Party hopes to clear some of its £12m overdraft by selling books through an online store, including some written by Labour leaders.
David Blunkett, Peter Mandelson, Paul Flynn and Tony Banks are among the Labour authors selling their books through the Tory site.
Flynn, whose book Commons Knowledge: How to be a Backbencher is on sale through the Tory site, explained that he did not mind propping up the ailing Tory Party with his book.
"I am delighted to know that my work is helping a party that finds itself in such an unfortunate position," he told the ePolitix.com website. "They are a far more deserving case than I am."
The site sells items ranging from DVDs of White House TV drama The West Wing to mugs with the slogan 'Don't Blame Me - I Voted Conservative' and Tony Blair golf balls.
Tory vice chairman Roger Gale said: "The internet is just one of the ways in which the Conservative Party is broadening its funding base and encouraging a larger number of small donations.
"We intend to show that state funding of political parties is not inevitable."
