David Cameron told MPs that lobbying is a "necessary and healthy part of the democratic process", during a grilling for his role lobbying government on behalf of the now-collapsed supply chain finance firm Greensill Capital.

The former prime minister Cameron is at the centre of a scandal around lobbying following revelations he lobbied the Bank of England and the Treasury for access to the government's Covid corporate financing facility, which was set up to help businesses access emergency funds during the crisis, months before the collapse of the firm.
