Former home secretary David Blunkett said there will not be an "unseemly public debate" over his former lover's children as he signalled his return to high-profile campaigning this week.

Following the Sun's disclosure that DNA testing had shown Blunkett was not the father of Kimberly Quinn's second son, her husband, Stephen Quinn, issued a statement accusing Blunkett of trying to smear his wife.

Speaking on Sunday, Blunkett said he had acted on legal advice and accepted that the second son was now "entirely their affair".
