David Cameron, the Prime Minister of the UK has arrived in India's financial capital, Mumbai with the largest trade delegation taken abroad by a British prime minister for a three day visit to the emerging country.

Cameron also expressed interest in the plans to develop the Mumbai-Bangalore development corridor. He said that he wants British companies to help develop new cities and districts along a 1,000 km corridor between the Mumbai and Bangalore. The plans are to generate investment projects worth as much as $25 billion.

He said that he wants British firms to work with the authorities in the UK and in India to participate in projects for the development of nine districts that are on the way from the financial capital to the software capital. Estimates shows that 5.8 per cent of the country's population growth would be along the corridor and they will contribute 11.8 per cent of the country's gross domestic product growth by 2020.

"With me I've got architects, planners and finance experts who can work out the complete solution. It would unleash India's potential along the 1,000 km from Mumbai to Bangalore, transforming lives and putting British businesses in prime position to secure valuable commercial deals," Cameron said.

He also urged the Indian government to open up the economy to allow foreign direct investment into different sectors.
