Jack Layton unveiled his 43-member shadow cabinet on Thursday with a promise that his team of 102 NDP MPs would refrain from the heckling and poor behaviour that has come to sully the tone in the House of Commons. Joe Comartin, Jack Harris and Paul Dewar will remain as the official critics of justice, defence and foreign affairs, respectively. Libby Davies has been moved to the health portfolio, previously the domain of Halifax MP Megan Leslie, who will move to environment. Peggy Nash will move to finance, while newcomer Jasbir Sandhu is now the public safety critic. Thomas Mulcair will remain as deputy leader.
