Harriet Harman: 'We have to get to the truth'
A committee of MPs will be asked to recall News International chairman James Murdoch to give more evidence on phone hacking.
Labour MP Tom Watson said he would also call for ex-News of the World editor Colin Myler and the paper's ex-legal manager Tom Crone to answer questions.
Labour deputy leader Harriet Harman said that Parliament needs to "get to the truth".
