LONDON, ENGLAND - FEBRUARY 24: A worker walks past royal mail vans at Royal Mail's Mount Pleasant depot on February 24, 2009 in London, England. Postal workers are preparing to protest in Westminster today amid growing anger over the proposed sale of a section of the business. Ministers want to sell a stake of about 30% to the private sector to help pay for the modernisation of the service. (Photo by Dan Kitwood/Getty Images)
