**Egyptian President Hosni Mubarak will undergo gall bladder surgery in Germany on Saturday, state TV has announced.**It said the 81-year-old president complained of gall bladder pain while in Germany for talks with Chancellor Angela Merkel.
Prime Minister Ahmad Nazif will act as president until Mr Mubarak returns, the report added.
Correspondents say Mr Mubarak’s health is usually a taboo subject in the country.
In 2004, he underwent back surgery - also in Germany - and handed over power temporarily to his prime minister.
And in 2003, he collapsed during a televised speech in parliament, apparently from a bout of flu.
Mr Mubarak has been president since 1981, and is one of the Arab world’s longest serving leaders.
