OTTAWA - Which federal political party speaks up most for Canadian women? The NDP will make its case this afternoon, when women MPs will ask all the party's questions in the House of Commons. NDP Leader Jack Layton usually asks his party's first question of the government in Question Period. With Layton on the shelf after hip surgery, deputy leader Thomas Mulcair has been doing the honours. But on Tuesday, Libby Davies will lead off the party's questions, followed by Carol Hughes, Irene Mathyssen, Linda Duncan, Niki Ashton, Jean Crowder, Chris Charlton and Megan Leslie.
