The home of Conservative shadow defence secretary Liam Fox has been burgled.
Details of the break-in at the central London property emerged on the day quarterly crime statistics for England and Wales were being published by the Home Office.
Mr Fox had been due to outline the Tories' armed forces manifesto but the launch was cancelled at short notice.
A Scotland Yard spokesman said: "Police were called at 7.20am to an address in SE1 to reports of a burglary.
"Officers are currently in attendance and the burglary squad from Southwark are investigating."
There have been no arrests, the spokesman added.
A Conservative spokesman said: "I can confirm that Liam Fox's car was stolen last night and police are investigating."
