The scheme is set to charge £4.80 per hour to park in the West End on evenings and weekends and will raise £7 million a year in tax for the London council. But this must be offset against the threat to jobs which could cost as much as £800 million says a study commissioned by local businesses worried about the impact of the new tax and carried out by independent city forecasters The Centre for Economics and Business Research. The businesses that will lose most are restaurants, bars, pubs and cafes and Michel Roux voicing objections to the plan said that his Mayfair restaurant Le Gavroche could lose up to 15 staff when the new tax comes in. "There is no congestion problem in Mayfair and never has been since I came here 30 years ago. Some staff would have to be let go because less money will be spent in the restaurant and some would leave voluntarily as they would not be able to afford to park their cars." He has been joined by many business leaders and politicians expressing their concerns about the tax having a very negative long lasting effect on the West End. Labour MP Karen Buck said "The evidence is piling up that these plans will have a counter productive and potentially dangerous impact on a vital part of London's economy." Westminster council did not carry out any research into the effect of its new tax and their cabinet minister for parking, Lee Rowley dismissed the independent research carried out as "completely flawed guesswork".
