LONDON—Britain’s former prime minister David Cameron said he accepted that communications with government needed to be done through formal channels after the row about his lobbying activities for financier Lex Greensill deepened on Sunday.
Cameron, who was prime minister from 2010 to 2016, appointed the Australian banker as an adviser when he was in Downing Street. After leaving office, Cameron in turn became an adviser to Greensill’s now-insolvent finance firm.
