British Prime Minister David Cameron on Friday said a time will soon come when there will be a British-Indian prime minister. Addressing 60,000 wildly cheering British-Indians awaiting to listen to visiting Indian Prime Minister Narendra Modi, Cameron began with an Indian style of greeting: "Namaste Wembley!" "It won't be long before there is a British-Indian prime minister in 10, Downing Street," Cameron said citing the contributions of British-Indians in various fields. He said that "India-UK ties are about people and about prosperity". "PM Modi and I govern in challenging times but we are united by the scale of our ambition," he said.
