The mayor of London has used Japan's role in World War II to attack its embassy in London for refusing to pay a controversial road charge.
Commenting recently about Japan's decision not to contribute toward the central London congestion motoring charge, Ken Livingstone told the LBC radio station, "I think there are several problems with Japan that we could go on about here.
"Admitting their guilt for all the war crimes would be one thing. So if they've not got round to doing that, I doubt they're too worried about the congestion charge."
His characteristically undiplomatic remarks have been rejected by the Japanese Embassy in London, which said Japan has already apologized for past atrocities.
