Peter MacKay just latest loss for federal Conservatives

The news that Justice Minister Peter MacKay will not run in the upcoming federal election is just the latest in a long line of Conservative cabinet and caucus members who aren't seeking re-election.

The veteran Nova Scotia MP has held several senior cabinet positions since the Conservatives took power in 2006, including foreign affairs and defence, after serving as the last leader of the now-defunct Progressive Conservative Party.

He joins other high-profile Conservatives who have left, or have announced they are leaving, federal politics.

Former foreign affairs minister John Baird stepped down as MP for Ottawa West-Nepean this past March. His 20-year political career began as an Ontario MPP before he was elected federally in 2006.

International Development Minister Christian Paradis announced in April he will not seek re-election for the Quebec riding of Mégantic-L'Érable. Since he was first elected in 2006, he has held several cabinet positions, including minister of public works and government services, minister of natural resources and minister of industry.

Heritage Minister Shelly Glover also announced in April that she will not seek re-election for the Winnipeg riding of St. Boniface. She was first elected in 2008.

Calgary MP Diane Ablonczy will not run after more than 20 years representing the Reform, Canadian Alliance and Conservative parties in the House. Under Harper, she has filled various roles, including minister of state of foreign affairs (Americas and consular affairs), minister of state for seniors, minister of state for small business and tourism and parliamentary secretary to the minister of finance.

Gordon O'Connor, who has been MP for the Ontario riding of Carleton-Mississippi Mills since 2004, is not running in the next election. He held various positions between 2006 and 2013, including minister of national defence, minister of national revenue and chief government whip.

Barrie MP Patrick Brown resigned this spring after winning the leadership in of the Ontario PC party. Alberta MP Brian Jean also resigned last year to run, successfully, for the leadership of Alberta's Wildrose Party.
