Pakistan is blighted by rolling power cuts, caused in part by people not paying their bills, with government offices among the worst offenders.

Ordinary people struggle without electricity for 12 to 18 hours a day in the blistering heat of summer, but up to now little action has been taken against recalcitrant bureaucrats working in air-conditioned offices.

The Capital Development Authority, Islamabad's civic agency which is responsible for paying government offices' bills, owes the Islamabad Electricity Supply Company (IESCO) 2.36 billion rupees ($24 million).

Power company officials said that electricity supply to more than 100 government offices had been disconnected over non-payment of bills.

Solving Pakistan's energy crisis was a key campaign pledge for Prime Minister Nawaz Sharif in the runup to the 2013 general election.

The disconnections were not limited to electricity. The state-run gas company also disconnected the natural gas supply to the prime minister's offices.
