Islamabad, Jul 10 (IANS): Former interior minister Rehman Malik, who is now adviser to the Pakistani prime minister on internal affairs, Tuesday said he has resigned from the Senate, the upper house of parliament.

The Pakistan Peoples Party (PPP) lawmaker said he submitted his resignation Monday, and has informed the party leadership about his resignation, Geo News reported.

He said he also wanted to quit from the post of adviser. But Prime Minister Raja Pervez Ashraf asked him to continue.

The Supreme Court had earlier suspended Malik's Senate membership for holding dual nationality of Britain and Pakistan.

Malik said he told the court he had forfeited his British citizenship but he failed to provide sufficient documents.

A letter from the UK Border Agency (UKBA) issued May 29 informed the minister that his request to renounce his British citizenship has been granted.

The apex court recently also suspended the National Assembly membership of PPP lawmaker Farahnaz Ispahani, and issued notice to Finance Minister Abdul Hafeez Sheikh on similar grounds of holding dual nationality.

On Tuesday, Malik denied that an amendment in the dual nationality bill is being approved by parliament for his benefit.

He said he had applied for surrendering his British citizenship in 2008 and also left his British business on the advice of President Asif Ali Zardari.
