Tens of thousands of anti-government protesters swarmed towards Pakistan's parliament late on Tuesday night after using bolt cutters and cranes to swiftly remove barricades designed to keep them away from the most sensitive areas of the country's capital city.

An estimated 50,000 protesters, led by an opposition politician and a Canada-based cleric, had been holding demonstrations in Islamabad for five days to demand the resignation of the government led by prime minister Nawaz Sharif.

But until Tuesday they had held back on threats to move on Islamabad's "red zone" which houses parliament, the prime minister's office and most foreign embassies.

Such a move risked sparking a violent confrontation with police and the army, which in an unusual move had in recent weeks been called in to buttress security in the capital, with about 700 personnel posted inside the red zone.

The challenge from the protesters puts Sharif in a difficult position. Major bloodshed defending the red zone could create the conditions for intervention by the country's powerful army, which has a long record of sacking civilian governments throughout Pakistan's turbulent history.

At the risk of looking weak, Sharif opted to allow the demonstrators to move into the heart of the capital.

No attempt was made to block the progress of marchers by police, many of whom were armed with nothing more than sticks.

Protesters were even able to drive cranes into the capital to remove stacks of sea containers placed on key roads leading to the red zone.

In a tweet, his daughter Maryam Sharif said the prime minister had ordered police "not to use any kind of force against the protesters" in order to protect the many women and children among them.

Imran Khan, one of the leaders of the demonstrations, deliberately put women and children at the head of the marchers, while he was conveyed with senior party members on the roof of a specially converted sea container.

Despite repeatedly claiming in a speech earlier in the evening that he would lead a peaceful demonstration, many of his supporters carried sticks and were prepared for tear gas with goggles.

Khan, the leader of the Pakistan Tehreek-e-Insaf (PTI) party, is demanding the resignation of Sharif's government which he claims won a landslide victory in last year's general election on the basis of massive electoral fraud, although his allegations have not been supported by independent observers.

He has promised to turn the area in front of Pakistan's national assembly building into a "Tahrir Square", referring to the 2011 protests in Cairo that ousted president Hosni Mubarak.

On Monday he also announced the 34 members of his party who won seats will quit parliament.

He has joined forces with Tahir-ul-Qadri, a Barelvi cleric with a considerable support base, who also wants to see the resignation of the government.

Unlike Khan, Qadri does not want fresh elections but the establishment of a "national government" of technocrats.

The protests in the capital have already gone on for five days. The prospect of the standoff continuing outside the nation's parliament could see the army playing an arbitration role.

Late on Tuesday army spokesman General Asim Bajwa tweeted an appeal for "patience, wisdom [and] sagacity from all stakeholders through larger national and public interest".

Over the last year Sharif has been weakened by damaging disputes with the powerful military establishment which removed him from power in the 1999 coup led by Pervez Musharraf.

Despite an outright parliamentary majority, the ongoing political crisis is likely to weaken him further and could make him reliant on the army for his political survival.
