Amid fears the Supreme Court would rule against him on the re-election challenges, Musharraf declared emergency rule nearly three weeks ago, suspended the constitution, sacked the chief justice and purged the court, installing more amenable judges. The move drew widespread international condemnation.
"He has assured me he will do his utmost to lift the state of emergency in time for free and fair elections to be held and to give up his military role and responsibilities as soon as possible," British Prime Minister Gordon Brown said before heading to a Commonwealth summit in Kampala.
The government has appealed to the Commonwealth of 53 nations not to follow through on a threat to suspend Pakistan for failing to meet a Thursday deadline to end emergency rule and reverse other authoritarian steps.
Western governments fear that stifling democracy could play into the hands of Islamist militants threatening nuclear-armed Pakistan.
Some Pakistanis say Bush's support of Musharraf -- describing him as a valuable ally, a man of his word and committed to democracy -- is part of the problem.
"I am very angry with the attitude (Bush) is having towards the country, because he should realise that we as a nation have given him support," said human rights activist Shahnaz Bukhari, chief coordinator of the Progressive Women's Association.
"He should not think that what he is doing and what he is saying is good for our country ... When American people come here they feel very insecure -- these are the reasons," she added. "Bush is having this (kind of) democracy in the USA?"
Musharraf has started to roll back the emergency, freeing around 5,000 lawyers, opposition and rights activists detained in a round-up of opponents. Those freed include Imran Khan, the cricketer-turned-politician.
Many of the judges and leading lawyers who represented the strongest challenge to Musharraf's authority are still in prison or under house arrest.
Musharraf remains in danger of political isolation.
Opposition parties led by Benazir Bhutto, the prime minister Musharraf allowed back to Pakistan, and Nawaz Sharif, the premier he deposed eight year ago and has kept exiled in Saudi Arabia, have yet to come up with a common strategy.
An opposition boycott could undermine the poll's credibility, but Bhutto may not want to gift Musharraf's allies a walkover.
