Israeli Prime Minister Ariel Sharon's son - Omri Sharon - has pleaded guilty to charges of illegally raising funds for his father's election campaign six years ago.

At the opening of his trial in Tel Aviv Tuesday, the younger Sharon's lawyer says his client admitted to charges of falsifying documents, perjury and violating the party funding law.

Under the charges, Omri Sharon - a Likud Party lawmaker and a key advisor to his father - could face a long prison term. But his lawyer is seeking a lighter sentence.

The case has embarrassed Prime Minister Sharon, but he himself was not charged with any wrongdoing.

Allegations that companies were set up to funnel foreign funds for Mr. Sharon's successful 1999 bid for the Likud Party leadership have fueled political opposition to the prime minister.
