Harriet Harman has said that Labour was right to investigate claims that Unite tried to rig the selection of a party candidate in Falkirk.
The party is under pressure to publish an internal report that cleared the trade union, finding that no rules were broken.
Labour's deputy leader was asked if Ed Miliband should apologise to Unite.
