Does two make a trend? This time, Chinese Prime Minister Wen Jiabao had a shoe chucked at his head during a visit to Cambridge University.

Before the guards could stop him, the unidentified protester took off his shoe, a heavy grey trainer, and threw it at the stage, missing Mr Wen by a few feet. Two large security guards immediately moved on to the stage at the West Road Concert Hall to shield the Prime Minister.
