Gangnam rapper Psy is mobbed by fans on his arrival in London ahead of speech at historic union

Gangnam Style rapper Psy was mobbed by screaming fans as he arrived in London today before heading to Oxford Union to give a speech.
The 34-year-old South Korean, whose music video is the second most watched YouTube clip in history, is the first east Asian pop star to address the historic organisation.
The speech will be Psy's first public address in English, and he has picked the perfect venue - an organisation that Harold Macmillan once called 'the last bastion of free speech in the Western world'.
