A year after Jack Layton lost his battle with cancer, NDP deputy leader Libby Davies says his leadership still lives on in the party. “The work that Jack did, I mean, he gave a legacy not just to the NDP, but to all Canadians,” said the MP for Vancouver East over the phone from Toronto. “And that’s something that’s very much alive.”..“People can feel very cynical about politics and politicians,” said Davies. “And I think in Jack they saw someone who was constructive, who always looked for a way to propose what should be done instead of a way of deposing something.”
