Pakistan Prime Minister Raja Pervaiz Ashraf has recently agreed to write to the Swiss authorities to invite them to reopen a corruption case against President Asif Ali Zardari, following an order to do so from the Supreme Court of Pakistan.

Allegations of corruption against President Zardari date back to the 1990s, when the President's late wife, Benazir Bhutto, was in power as Prime Minister. Formal investigations were previously carried out by the Swiss authorities into allegations of money laundering using President Zardari's Swiss bank accounts. The investigations ceased when the Pakistani government intervened in 2008.

Whilst the new letter from Prime Minister Raja Pervaiz Ashraf invites the Swiss authorities to reopen the corruption case, it is not know what immediate steps can be taken as Switzerland recognises President Zardari's immunity as head of state.
