Pakistan: Day Three of the Long March

4:30 p.m. GMT: It appears that the Zardari Government is trying to reach a settlement with the Pakistan Muslim League (N) party of Nawaz Sharif by announcing that it would file a review petition in the Supreme Court against the disqualification of Sharif and his brother Shahbaz from public office. The PML (N) is not conceding ground, however, on its demand for the restoration of deposed judges.

1:20 p.m. GMT: Despite roadblocks and detentions under Section 144, smaller groups of protestors are making their way to Lahore. Interior Minister Rehman Malik has announced restrictions on protests in the Pakistani capital, notably no processions or sit-ins on Constitution Avenue in the capital city, while claiming to have discussed alternate venues with Long March organisers. He is also warning of the possibility of a suicide or targeted attack at the venue of the Long March sit-in.

An emergency meeting of the ruling Pakistan People's Party has been called for this evening. Earlier rumours of a possible deal between Asif Zardari and Nawaz Sharif over a Charter of Democracy seem to have been nipped in the bud by the President: "I am not going to negotiate under pressure. Mr Sharif has to abandon the Long March.”

8:15 a.m. GMT: Pakistani authorities have again prevented Ahmed Ali Kurd, the President of the Bar Association, from reaching Lahore. Two days after his convoy was halted, Kurd and his travelling party were not allowed to board a plane.

7:30 a.m. GMT: The Long March is expected to reach Lahore today. Despite the political manoeuvring yesterday pointing to a possible compromise between President Asif Ali Zardari and his opponents, Government forces moved against demonstrators overnight. The Vice President of the Bar Association, Saeed Akhtar Khan, has been put under house arrest.

Zardari has come under further pressure from within his Government, as Information Minister Sherry Rahman, formerly a close ally of the President, resigned. She is reportedly angry over a Government clamp-down on the media, including the closure of private channel Geo News.

Al Jazeera are also reporting angry exchanges between Zardari and the head of the military, Ashfaq Parvez Kiani.

Pakistan: Day Two of the Long March

update (8 p.m. GMT): The Zardari Government has met in emergency session. The President has been joined by Prime Minister Gillani, Senate Chairman Farooq Naek, Interior Minister Rehman Malik, Information Minister Sherry Rehman, and Water and Power Minister Raja Pervez Ashraf. Spokesmen are promising "important decisions" within 24 hours.

Update (5 p.m. GMT): High-level talks appear to have begun in Pakistan. The reasons for movement are unclear.

One possibility is that a call from US envoy Richard Holbrooke to President Zardari, following a meeting between the US Ambassador to Pakistan, Anne Patterson, and Nawaz Sharif, has pushed the Government to a more conciliatory position. The US and UK have both denied putting any pressure on Zardari to make concessions to the marchers, though Foreign Secretary David Miliband's office have confirmed that he has spoken to Zardari by telephone.

Update (2.30 p.m. GMT): Former Supreme Court Bar Association President Aitzaz Ahsan has said that the Long March will be called off if Iftikhar Chaudhry is reinstated.

Update (1.45 p.m. GMT): Dawn sources claim that President Zardari may have accepted some of the compromises suggested by PM Gilani.

Update (12 p.m. GMT / 5 p.m. Pakistan): There are rumours that PM Yousaf Raza Gilani is pushing for a compromise, and that President Zardari may be willing to yield to some of the marchers' demands. However police have sealed the Punjab-Sindh border and closed highways to prevent the marchers reaching Multan.

Update (9 a.m. GMT): The Pakistani Government has invoked Section 144, the order authorising detention of demonstrators in the Northwest Frontier Provinces, detaining dozens of people.

There were no reports of further arrests overnight. The most significant incident was the blocking of a convoy from Quetta with Ali Ahmed Kurd, the President of the Supreme Court Bar Association. Kurd and the convoy have responded with a sit-in blocking the main highway from Baluchistan to Sindh Province.
