DEFRA's official ministerial cars are all hybrid, with two Toyota Prius cars (1.5 litre petrol/electric) and two Honda Civic Hybrid cars (1.4 litre). The Secretary of State's car is a Toyota Prius.
The Government Car and Despatch Agency (GCDA) is responsible for providing ministerial cars in line with the Ministerial Code and the Prime Minister's guidance 'Travel by Ministers'.
GCDA advises the Prime Minister on the suitability of cars for inclusion in his guidance, taking into account a number of criteria when assessing suitable cars including their environmental impact, running and maintenance costs and overall suitability as a ministerial car.
Lord Rooker and Helen Ghosh have both given up their GDCA allocated cars, but occasionally use GDCA pool cars and green cars where necessary, and there is no viable public transport alternative.
