Pakistan's president, Asif Ali Zardari, is due to visit India on Friday - the first visit by a Pakistani president since 2005.
Althought the visit is said to be a private pilgrimage to the shrine of Sufu saint in Ajmer, Rajasthan, President Zardari will have lunch with India's Prime Minister, Manmohan Singh in New Delhi.
The visit is being seen as a sign of improving relations between the two countries.
