David Cameron has admitted he owes an apology to former Conservative party treasurer Peter Cruddas, who was made an "outcast" by the party after newspaper sleaze allegations.
Mr Cruddas was dismissed from the role after the Sunday Times reported that he was charging £250,000 to meet Mr Cameron but has since won a libel action against the newspaper.
High Court judge Mr Justice Tugendhat criticised the Prime Minister's response, saying he had subjected his former Conservative colleague to a "public humiliation".
Mr Cameron said he was "very sorry" about the treatment of Mr Cruddas, who claimed he was "cut off" by the party and "made to feel like an outcast" by the Prime Minister.
Mr Cameron said he was looking forward to meeting his former colleague later in the year.
He said: "I rather think I do owe him an apology."
