British Prime Minister David Cameron has described Sachin Tendulkar as the greatest of all times. He also wished him good luck for his ongoing 200th Test match against the West Indies in Mumbai. Interacting with the Indian businessmen in Delhi today, Mr Cameron said, it's not just about cricket but also the consistency one needs to score a century. Noting that Tendulkar has inspired a lot of youth, he said Sachin has done more to inspire the young cricketers. The British Prime Minister also sent a framed photograph signed by him of Tendulkar walking out of Old Trafford ground along with his then team-mate Manoj Prabhakar after scoring his maiden Test hundred against England in August 1990. Cameron wrote in ink below the photograph:"From the first of 100 centuries to your 200th and final test – congratulation on a career that will inspire millions for generations to come."
