British Deputy Prime Minister Nick Clegg said energy and climate change would be near the top of his agenda during a three-day visit to India.

"There is already $26.5 billion of trade every year between India and the U.K.," he said before leaving Monday. "India invests more in the UK than it does in the rest of the European Union combined, and no country in the G20 invests more in India than Britain does."

The deputy prime minister led a delegation to India this week to discuss British opportunities in the growing Indian economy. His office said climate change and energy were expected to be near the top of the agenda for this week's meetings.

A report from financial firm Dun & Bradstreet said last week the Indian gross domestic product should grow by 5.5 percent next year, up from the 5.2 percent expected this year.

Dun & Bradstreet India Senior Economist Arun Singh said it should be a vibrant era for the nation's economy in the years ahead.

"India is likely to achieve a higher average growth rate of around 7.5 per cent during fiscal years 2015-20, spurred by large infrastructure investment by the government along with increased investment activity by the private sector," Singh said.
