I know from my own experience how vital it is when trying to clean up air in a great city not to penalise business unjustly, and particularly small businesses. It has become clear that the scheme proposed by the Labour Mayor in Manchester is completely unworkable and will do more damage to businesses and residents in Manchester. We must find an alternative that does not punish local residents. My right hon. Friend the Secretary of State for Environment, Food and Rural Affairs will say more about that in the coming days.
