Islamabad: Pakistan's defence spending has exceeded budgetary limits for the first six months of current fiscal by about Rs 60 billion.

This happened due to the enhanced expenditure on the war on terror and the military's prolonged engagements in the tribal belt.

Under a federal spending plan put in place by the Finance Ministry, defence expenditure in the first six months of the financial year should have been around Rs 175 billion but actual spending had exceeded Rs 235 billion.

The government had envisaged Rs 442 billion as defence spending for the current fiscal year.

Higher than expected expenditure and lower than anticipated revenue collection in the first half of the year were offset by a tight squeeze on the development programme that has been restricted to Rs 88 billion in almost seven-and-a-half months of the year, the official said.
