Routine journeys carried out by millions of British motorists can be
monitored by authorities in the United States and other enforcement
agencies across the world under anti-terrorism rules introduced
discreetly by Jacqui Smith.

Sources said that officers would access the cameras on behalf of
overseas authorities if they were informed about a terrorism threat in
the UK or elsewhere. They would then share the images, which can be held
for five years before being destroyed, if necessary.

Last night, Nick Clegg, the Liberal Democrat leader, said: "This
confirms that this Government is happy to hand over potentially huge
amounts of information on British citizens under the catch-all pretext
of 'national security'."

Civil liberties campaigners said they were appalled that images of
innocent people's journeys could end up in the hands of the British
police, let alone foreign investigators.

They feared that it was a move towards the US-style system of "data
mining" - in which powerful computers sifted millions of pieces of
information as they tried to build patterns of behaviour and match them
to material about suspects.
