JAPANESE Emperor Akihito arrived in Britain on a State visit last night, with protests awaiting him today from veterans over the wartime treatment of British prisoners.

There was an early indication of the public mood when about 20 survivors of the internment and labour camps held a candle-lit vigil outside the Japanese embassy in Piccadilly. They were remembering the 13,433 Britons who died in captivity and the many thousands whose lives were blighted by their ordeal.

Demonstrations are planned throughout the visit as part of a campaign for compensation and a full apology. Mr Blair believes the veterans have a right to demonstrate, but should do so in a ''dignified and peaceful way''.

Hundreds plan to line The Mall today and turn their back on Akihito while whistling Colonel Bogey, as a mark of disrespect.
