Unearthing sleazy dealings between errant corporate bigwigs and wayward politicians is easier said than done. Both sides gain from such illicit transactions, so don't expect anyone to talk. Try asking anyone in Umno.

Despite all the hot air on money politics (read: vote buying) in that's party's recent polls, not a single soul has yet to come forward to finger the wrongdoers. Clearly, given the consequences, few would dare.

One Umno leader even mooted some sort of a witness protection programme for whistleblowers - such is the depths of desperation roiling the country's premier political party.

But sometimes a very rare sometimes - we do get lucky. This could come in the form of a document dropped into our mailbox, a phone call from a total stranger, or more likely these days, an anonymous email.

That was how we stumbled on the Iraq Survey Group report.
