Experts warns 'we look weak' over London's Chinese super-embassy

China's new super-embassy could be used to spy on the whole of Europe, a security expert warned today - as plans revealed a secret chamber next to sensitive cables. Un-redacted papers - unveiled last night - supposedly show a hidden room in the north west corner of the building - just metres away from a vital fibre-optic cable network transmitting financial data from the City of London and Canary Wharf. Professor Anthony Glees, a professor of intelligence and security at University of Buckingham, said it would be 'absolutely mad' to allow China to proceed with the development.
