Yousuf Raza Gilani, the Pakistani prime minister, is preparing to visit parts of the country that have been devastated by flooding.

More than five million people have been affected by the floods, and 300,000 are now living in emergency shelters. Many say they are yet to see any form of aid, despite pledges from both the government and international agencies.
