Coming from the director of the Brighton Economic forum, Tony Mernagh's points about the proposed park-and-ride are extremely interesting.

He says each 1,000 park-and-ride spaces would mean a reduction in pollution due to 700,000 fewer vehicle movements in the city and a reduction in 330 tonnes of CO2 gases each year.

However, this can only be achieved by a corresponding reduction in town-centre parking spaces.

So, Tony, here's a direct question you have so far avoided answering: Do your park-and-ride proposals mean a corresponding reduction in town-centre parking spaces or not?
