A party spokesman said Lorraine Kane had been asked about quotes in the Daily Mail suggesting she had not intended to retract her complaint about alleged irregularities in the candidate selection process.
However, she confirmed that she stood by the sworn statement given to the party's probe in September, according to the spokesman.
It was that affidavit which was part of the reason that led the Labour Party to conclude there was insufficient evidence to proceed with our inquiry.
Therefore we have not seen any new evidence to justify further action.
