So will the disclosure that so far 48 people have been questioned by police in connection with the inquiry.
Let me make clear at the outset that I am not trying to score cheap party political points in this unappetising affair. No party can be sure that it is entirely clean when the issue of political funding and favours is raised.
However, I think I might be forgiven for pointing out some delicious ironies.
Tony Blair came to power after campaigning vociferously against so-called "Tory sleaze" and promised to be "whiter than white" when it came to matters of political probity and integrity. Others can decide whether he has kept that promise.
His chief cheerleader in this campaign was none other than John Prescott. In opposition he was always quick to raise the moral standard to shriek about sleaze in his inimitable style. Today the Deputy Prime Minister's humiliation continues as one by one his jobs and now his perks are taken away following his own questionable conduct.
Political parties run on a shoe-string. The annual turnover of the Conservative Party HQ is only £15 million - far less than that of major charities such as the RSPCA, which spends six times as much.
But even though parties are short of cash, that is no excuse in today's Britain for allowing anyone to buy personal advancement or influence over policy.
At the end of this sorry affair, that principle will need to be reinforced.
