A new report today claims more than 200,000 jobs in the Thames Valley will be lost if Heathrow is forced to close.
It examined the economic impact along the M3 and M4 from Heathrow to Basingstoke, Guildford, Newbury and Oxford and concluded that one in 20 jobs in the region were in some way linked to Heathrow. London Mayor Boris Johnson says Heathrow should close with a new airport built in the Thames Estuary.
The research was carried out by Regeneris, an economic consultancy, and was paid for by local enterprise partnerships including Buckinghamshire Thames Valley, Enterprise M3, Oxfordshire and Thames Valley Berkshire. The Government is consulting on where new runways should be built in the region.
