British Prime Minister David Cameron began Monday an official visit to India for talks with his Indian counterpart Manmohan Singh in New Delhi on Tuesday, expected to focus on trade and commerce issues. Cameron and the accompanying delegation arrived this morning in the financial hub of Mumbai for a business meeting later in the day, according to a report of DPA. India and Britain will also seek to boost economic ties. Two-way trade in the last financial year rose to $16 billion, up 27 per cent from the previous year. Cooperation in energy, counter-terrorism and regional security would also be discussed in Cameron's second visit since becoming Prime Minister in May 2010.
