Thousands of people have rallied in the capital against government corruption.
The Pakistani Supreme Court has issued an arrest order for Raja Pervez Ashraf, the country's prime minister.
The order stems back to a case on rental power agreements when the now prime minister served as the federal minister for water and power.
Raza Rumi, editor of The Friday Times, a Pakistani newspaper, told Al Jazeera the high court's order "came as a bit of a surprise and a shock. It definitely puts immense pressure on the elected government in Islamabad, which is already buckling under".
Speaking to Al Jazeera from Islamabad, Rumi said with the leading Pakistan People's Party "due for an election", the "uncertainty" created by the arrest order puts into question whether the nation can or will hold upcoming elections.
