A senior Daily Mail journalist has suggested tonight that his newspaper may have made a mistake over the row with Labour leader Ed Miliband.
Alex Brummer said the controversial article accusing Mr Miliband's late father of "hating Britain" should have been presented more clearly as comment.
Labour have seized on the remarks as a sign that the newspaper's defence is crumbling.
Both the Editor and owner of the Mail on Sunday have apologised for a reporter intruding on a private memorial for Ed Miliband's uncle.
Ed Miliband has written to the Daily Mail's chairman Lord Rothermere to complain about a reporter attending his uncle's memorial service.
The PCC said it had received 384 complaints by 4pm on Wednesday relating to Daily Mail articles about Ed Miliband's father.
