Interim federal Liberal Leader Bob Rae.
Bob Rae, former interim Liberal leader and one-time NDP premier of Ontario, is resigning as an MP, winding up a political career that stretched over 35 years and two parties.
Rae says he is leaving in order to focus on his new role as chief negotiator for First Nations in talks with the province about development of the Ring of Fire mining development in northern Ontario.
Rae began in politics as a New Democrat and later shifted to the federal Liberals, even seeking the party leadership at one point.
He was first elected to the Commons in a 1978 byelection, but moved to Ontario provincial politics four years later, when he became provincial NDP leader.
He was premier from 1990-95 during troubled economic times and left a controversial legacy.
In 2006, having joined the Liberals, he unsuccessfully sought the party leadership, but won a seat in the Commons in 2008, becoming interim leader after Michael Ignatieff lost his seat in the 2011 election.
