Queen Elizabeth II's husband, Prince Philip, has shocked a Bangladeshi teenager in London after allegedly branding him a drug addict.

The 81-year-old prince pointed out 14-year-old Shahin Ullah at a London youth club and commented, "He looks as if he is on drugs."

He was visiting the Bangladesh Youth Club in Marylebone when he sat down with some of Shahin's friends and asked, "So, who's on drugs here?"

Shahin is quoted in the British media as saying he had never taken drugs in his life and had been shocked when the "rude" prince singled him out during a visit to the club and claimed he looked like an addict.

"He called me a druggie when I am not a druggie", Shahin said. " I didn't like that and my friends did not like that. I was very upset. Just because he is rich and has money does not mean he can say anything to anyone."

Philip was at the club earlier this month as he conducted a series of visits to inner city youth organisations. During the half hour visit, he sat down for what officials at Buckingham Palace said was an "informal chat" with several youngsters during which the discussion turned to drugs.

In a separate controversy earlier this year, Philip reportedly asked British Indian Labour MP Parmjit Dhanda what he did before becoming an MP. When 31-year-old Dhanda replied that he had been a student and then trade union official, the prince replied: "So you didn't do anything then."

When Dhanda responded by asking, "What did you do before becoming the Prince of Edinburgh?" Philip replied, "I served in the Royal Navy during the war" and delivered a two-fingered salute before turning on his heel and walking off.
