The last time a leader from Communist China, Jiang Zemin, was feted by the British Government on a State visit, back in 1999, there were arrests of peaceful "Free Tibet" demonstrators, confiscation of flags and banners etc.
What will happen this time with the vist of Hu Jintao who arrives in London for a 3 day State visit, now that the extra Serious Organised Crime and Police Act 2005 Designated Area penalties are in force, covering many of the venues where the increasingly authoritarian and repressive leader will meet his Chinese counterpart., and at which peaceful demonstrators will be present. ?
