An extraordinary spat between two of the bodies responsible for enforcing electoral law. Yesterday the Metropolitan Police launched a stinging attack on the Electoral Commission, saying they still haven’t been sent paperwork relating to claims made by the Vote Leave whistleblower, Shahmir Sanni. His claims – that the official leave campaign, Vote Leave, had broken election spending rules during the 2016 referendum – were broadcast last year by this programme and others. It all raises questions about who is responsible for ensuring our elections are free and fair.
