World Anti-Doping Agency (WADA) president Craig Reedie is hoping to have an investigations fund of over $1million to step up action taken against drugs cheats ahead of the Olympic Games in Rio.
WADA last week named Canadian Richard McLaren as the man to lead an investigation into allegations doping at the Winter Olympic Games in Sochi two years ago.
McLaren was also part of WADA's three-person independent commission which uncovered widespread systematic doping in Russian athletics last year.
Reedie is optimistic that a seven-figure sum will be in the coffers to use for investigative work in the not too distant future.
He told insidethegames: "My guess is that by roughly the end of June I will have raised about $600,000 (£414,000/EUR535,000) from governments, and I will then formally write to the IOC (International Olympic Committee) and ask them to match it.
"If that comes about, I then have obviously up to $1.2 million (£827,000/EUR1 million) as an investigations fund."
