Environment Secretary Michael Gove announces plans to clampdown on all sources of pollution, including coal-burning and ammonia from farms. But he told Mishal Husain that it would be "disproportionate" to have a uniform ban on certain fuels. Mr Gove said the air pollution effects in rural areas of fuels, such as diesel or coal, are significantly less compared to urban areas as they are dispersed.
