“If the streets are safe, and if the transport links are there, and if there are good broadband connections, you enable new housing to go ahead, on brownfield sites that were never considered viable before. We enable young people to get a foot on the housing ladder and we enable people to live near the good jobs and above all – with safe streets and affordable housing and fantastic wifi – we give business the confidence to invest and to grow”.
