Pakistan Prime Minister Raja Pervez Ashraf says he will obey Tuesday’s Supreme Court order to reopen a corruption case against the country’s president.
Ashraf said he will cooperate with Swiss authorities in the investigation against President Asif Ali Zardari.
The head of state is accused of taking bribes from major corporations and then laundering the money in secret bank accounts in Switzerland.
Pakistan’s Supreme Court found Ashraf’s predecessor to be in contempt earlier this year for failing to act on an order to probe the allegations.
That ruling came after judges cancelled an amnesty in alleged graft cases.
But investigators will be unable to act quickly as Zardari enjoys immunity from prosecution as head of state.
He spent several years in jail in the 1990s and the start of the last decade over corruption allegations, but he always denied any wrongdoing.
