Prince William and his wife Kate will arrive in
Pakistan late Monday for their "most complex" tour to date,
British officials said, with Islamabad eager to tout improved security after years of violent militancy.
Details of the five-day visit are being kept under wraps, with security expected to be tight for the couple's first official trip to Pakistan, and the first visit by a British royal since William's father Charles and his wife Camilla came in 2006.
In addition to Islamabad they are set to visit the ancient Mughal capital of Lahore, as well as the mountainous north and the region near the border with
Afghanistan in the west, according to British High Commissioner Thomas Drew.
