The aircraft has been linked in the past to a shadowy fleet of surveillance planes said to be operated by the Met.... Reports suggest the planes, costing £3m a year, are used to monitor mobile phone calls.

Social media websites reported the aircraft flying from Farnborough Airport to south London for today's 'mission'.

A Scotland Yard spokesman declined to offer "acknowledgement or comment".

The video below show the plane circling over London at 10am today.
