Ranting Kanye West booed by festival crowd

US rapper Kanye West got London's Wireless festival off to a controversial start as he was booed on the opening night.
The 37-year-old musician, who topped the bill on the Main Stage on the opening day of the London leg in Finsbury Park, was heckled and festival-goers walked out after he indulged in an expletive-ridden rant during his 90-minute set.
