By Reza Sayah reporting from Islamabad
Pakistan is facing its most serious political crisis in years, with rapidly escalating conflicts between the civilian government, the military and the judiciary, against the backdrop of a faltering economy, widespread poverty, corruption and the bloody war with Islamist militant groups.
The country was founded in 1947 as a democracy, but in times of crisis the army - Pakistan's most powerful institution - has overthrown the civilian government on the grounds that the leadership had been unfit and corrupt.
Rumors of another coup have been swirling around the current crisis - but analysts say a military takeover is highly unlikely this time around.
