Former MP Bill Casey wants to run for federal Liberals next year

Bill Casey, the former Nova Scotia Member of Parliament for Cumberland-Colchester-Musquodoboit Valley, announced Tuesday he will be seeking the Liberal nomination in his former riding for the next federal election.

"There are several reasons for my interest in re-entering politics, but the issue that has motivated me to act now is that I want to add my voice to those very credible people who are raising the alarm about the declining state of our parliamentary system," Casey said in a statement released Tuesday.

"I believe that those of us who have experienced this deterioration first hand have an obligation to speak out."

Casey made headlines in 2007 when he was kicked out of Prime Minister Stephen Harper's Conservative caucus for voting against his government's budget.

He ran successfully as an Independent MP and held the seat until April 2009, when he retired to take a high-profile provincial government job.
