The next Mayor is faced with an air pollution crisis to solve and the knowledge that expanding our road network will just make that crisis worse. What we need is the same kind of determination as when London adopted the congestion charge. The only way London will work is if we reduce traffic at the same time as increasing our population. The next Mayor has to instil a sense of optimism into Transport for London. They have done it before, they can do it some more.
A year ago this week our mum died after she lost her third bout with Lymphoma. Today, in her memory, I set off on a 153-mile charity bike ride with one of my sisters, from the London hospital where mum had life-saving treatment in the 1980s to the Norwich hospital where she was cared for at the end of her life.
