MUMBAI, India (AP) — British Prime Minister David Cameron called on India to further open up to foreign investment and loosen regulations that hamper businesses, saying Monday that the countries’ “special relationship” could blossom into a powerful economic partnership.

On his second visit to Britain’s former colony, Cameron led a delegation of more than 100 British CEOS and investors and stopped first in Mumbai, India’s financial capital. He is to continue to New Delhi and meet with Prime Minister Manmohan Singh on Tuesday.
