Islamabad: Pakistani leaders failed to agree on a deal on restoring judges sacked by President Pervez Musharraf to stop legal challenges to his presidency.

Negotiators from the two main ruling parties held talks in London throughout the weekend, ahead of a self-imposed Monday deadline to resolve the issue.

However, officials said Sunday night they were heading back to Pakistan without a deal.

Without a deal, representatives of former prime minister Nawaz Sharif's party said members would meet Monday to consider whether to stay in the coalition.

Sharif, who was tossed out by Musharraf in a 1999 coup, has pushed for the president's ouster and demanded outright restoration of the deposed judges.
