Police are likely to recommend indicting Israeli Prime Minister Ehud Olmert on corruption charges within three days, Israeli media reported.

Newspaper and radio reports said police completed three of five corruption probes against Olmert and would probably advise the attorney-general to indict the Israeli prime minister, a process that could take weeks or even months.

Olmert has denied any wrongdoing.

The reports said police have enough evidence to recommend Olmert be indicted for taking bribes from an American businessman, making multiple claims for travel expenses and using a former ministerial post to advance the business interests of a friend.

Under Israeli law, police must submit their recommendations to the prosecution which then files its own legal opinion to the attorney-general, the only body authorised to indict a prime minister.

Olmert, who faces two other police probes, has said he would resign after his Kadima party picks his successor in a September 17 leadership vote. He could stay on as premier for weeks until his successor forms a new government.

Prospects of his resignation could imperil US-backed peace talks with Palestinian President Mahmoud Abbas. Olmert and Abbas launched the talks at a conference in Annapolis, Maryland last November with the goal of reaching an agreement this year.

But the negotiations have been marred by violence, as well as disputes over Jewish settlement building and Olmert's insistence that the fate of Jerusalem be decided later.
