Cameron met Prime Minister Manmohan Singh and sought to allay the concerns of students looking to pursue education in the UK, saying there was no limit on the number of Indian students wanting to go there. He, however, said the UK needed to keep a tab on immigration.

Prime Minister Manmohan Singh is not attending the Commonwealth Heads of Government Meeting in Colombo. External Affairs Minister Salman Khurshid is representing him at the summit of 53 countries, being held for the first time in Asia after two decades. The PM's decision followed protests from prominent Tamil parties over the alleged human rights violations by Sri Lanka during its war against the LTTE. 
Cameron said he respected Singh's decision not to attend the two-day CHOGM meeting.

During an interaction with Indian businessmen in New Delhi, Cameron said he was open to meeting elected leaders, including Gujarat's Chief Minister Narendra Modi, noting the UK has already started a "proper engagement."

Cameron also backed India for a permanent seat in the United Nations Security Council. "The UN ought to include India as a permanent member," Cameron told an interactive session with students of the Indian Institute of Management in Kolkata.

Cameron said the UK and India can effectively deal with various challenges such as combating terrorism by working closely with each other.

The main focus during Singh-Cameron talks at the Prime Minister's Race Course residence was on trade ties with the British leader maintaining there has been "extraordinary progress" on trade and investment since his first trip here.

The two leaders also shared a strong view on Sri Lanka over the human rights situation there.

Later, in a tweet after his meeting with Singh, Cameron said they agreed that extraordinary progress on trade and investment has been made since 2010.
