Ehud Olmert, Israel's prime minister, was under growing pressure to resign amid allegations that he received politically-motivated funding before he became head of the Israeli cabinet.
An investigation into the 15 years of funding is the latest incident to hit Olmert's once-glittering career.
A former mayor of Jerusalem, Olmert had built his political career on his reputation as an ally of Ariel Sharon, the former prime minister.
When a stroke left Sharon in a coma in January 2006, Olmert became acting prime minister and chairman of Sharon's Kadima party. And when Sharon failed to recover, Olmert became prime minister three months later.
Despite their political relationship, Sharon and Olmert were also rivals and in 1999 they squared off against each other to battle for the leadership of the Likud party, which Sharon won by a big margin.
In 2003, Sharon brought Olmert into his government as a deputy prime minister. He also held the trade and industry, communications and finance portfolios in Sharon's administration.
As mayor of Jerusalem, Olmert called for the expansion of Israeli settlements in the West Bank. However, during Sharon's second term as prime minister, Olmert supported his call for Israel's withdrawal from Gaza.

This enhanced Olmert's reputation as one of Likud's more dovish senior figures - while also cementing his reputation as one of Sharon's closest allies.
He continued to support Sharon throughout the withdrawal process, when illegal Israeli settlements were dismantled in Gaza and settlers evicted.
When Sharon left Likud to set up the Kadima party, Olmert was among the first to join him.
But his career as prime minister has been damaged, particularly after the publication of the Winograd Commission's interim report, which investigated his handling of the July 2006 war against Hezbollah in Lebanon.
The preliminary report found that Olmert had "no organised plan" in responding militarily to the cross-border raid by Hezbollah that sparked the conflict, and said his judgment was "misguided and rash".
Given that Israel failed to defeat Hezbollah fighters in southern Lebanon after 34 days of warfare, Olmert's approval ratings shrank.
Olmert's political life has been dogged by allegations of financial mismanagement.
In 1996, he was tried on charges of breaking Israeli law on party funding as Likud party treasurer during the 1988 elections although he was eventually cleared.
Olmert was investigated on suspicions of accepting bribes from a businessman during the so-called Greek Island affair, although prosecutors dropped the charges due to lack of evidence in 2004.
He has also faced allegations that, as trade minister in 2001, he helped push through a grant for a business linked to a colleague. Last week, the government watchdog recommended a criminal investigation.
As finance minister in 2005, Olmert allegedly tried to tip a government tender for sale of a major bank to a group of his backers, but failed.
Olmert was born in September 1945 near Binyamina, when Palestine was a British mandate.
He was first elected to the Knesset at the age of 28, and went on to work in the foreign affairs and security committees.

He got his first taste of government from 1988 to 1990, when he served as a minister-without-portfolio for minority issues in Yitzhak Shamir's national unity government.
Olmert was also health minister in the Likud government that followed and held that position for two years.
In 1993, Olmert became mayor of Jerusalem, beating the long-standing incumbent Teddy Kollek.
He served two full terms in the post, and oversaw changes to the city's education and transport systems, before quitting to become deputy prime minister.
He is married to Aliza, a writer, and the couple have five children.
