Alberta's ethics commissioner has rejected Opposition accusations that Premier Jason Kenney and his United Conservative caucus broke the rules when they fired an election official investigating the party.

The NDP alleges that the UCP caucus was in a conflict of interest because it benefited from the firing last month of elections commissioner Lorne Gibson.

Through the Edmonton Police Service, Democracy Watch requested an investigation, overseen by a special prosecutor, into whether Jason Kenney's cabinet obstructed justice by firing Lorne Gibson.

The ethics commissioner has responded to a request from Opposition Leader Rachel Notley, asking for UCP MLAs to be banned from voting on the contentious Bill 22.

Alberta's Opposition NDP is asking the ethics commissioner to ban the entire United Conservative caucus from voting on a bill that would fire the province's election watchdog.

Political analysts are calling the Alberta government's bluff after it announced on Monday it was firing the election commissioner.

Alberta's United Conservative government is firing the province's election commissioner, but says it's not because he is investigating the party and has fined it more than $200,000.
