This is what the SAGE Commission report had to say about GP cars:
“While many Government cars are driven from a government office to the user’s home and back again, GP-plated vehicles have often been observed in the parking lots of supermarkets, health clubs and golf courses.
This suggests that Government cars are not used strictly for Government business.
The Head of the Civil Service should review the use of Government cars and to whom such vehicles are assigned with a view to reducing the number of Government cars.
This review should include the use of Government cars by senior officers in the Police, Prisons, Fire, Regiment and Customs Service.”
