BBC News forms a major department of the Corporation, and receives many complaints of bias. The Centre for Policy Studies stated, "Since at least the mid-1980s, the Corporation has often been criticised for a perceived bias against those on the centre-right of politics". Similar allegations have been made by past and present employees such as Antony Jay, North American editor Justin Webb, former editor of the "Today" programme Rod Liddle, former correspondent Robin Aitken and Peter Sissons, a former news presenter.
