UK and India has decided to expand their trade and investment relations.

The visiting UK Prime Minister David Cameron, who is on his way to CHOGM Summit at Colombo, said he was open to meeting all elected leaders, including Gujarat Chief Minister Narendra Modi who is the BJP's prime ministerial nominee for the 2014 polls.

'Entirely yes...I am open to meeting all elected leaders anyway,' he said and added 'we have started some relations with Gujarat already. The connection and engagement is there.' .

The people of India will decide who becomes their Prime Minister in 2014, he said.

'In the end it will be for the people of India to decide who they elect,' said Cameron.

Cameron met the Indian Prime Minister Dr Manmohan Singh here on Thursday. In over an hour long talks at Dr. Singh's residence, the two leaders discussed bilateral, regional and international issues of mutual concern. Boosting economic cooperation, trade and investment figured prominently during the talks.

Earlier in the day he met leaders of Indian industry. He stressed for a more transparent regulatory framework for British companies doing business in India. Both India and Britain aims to double bilateral trade to 23 billion pounds by 2015.

Cameron also said, he respected Prime Minister Manmohan Singh's decision of not attending the Commonwealth Heads of Government (CHOGM) meeting in Sri Lanka. He said, India, Canada and Britain share the same approach towards Sri Lanka. Cameron said, his visit to Srilanka will help to throw light on these issues.

The UK Prime Minister had arrived in New Delhi last night. After talks with Dr Singh, he left for Kolkata where he will meet West Bengal Chief Minister Mamata Banerjee. He will also visit the Indian Institute of Management and All India Radio in Kolkata.

The British Prime Minister will later fly to Colombo to attend the Commonwealth Heads of Government Meeting on November 15-16.
