Andrew Coyne has resigned as editor of editorials and comment for the National Post over a disagreement over Postmedia’s endorsement of the Conservatives, although he’s staying on as a columnist, he announced on Twitter this morning.

In a string of tweets, Coyne explained that he disagreed with Postmedia executives over the endorsement, while his former bosses held the view that “the publication of a column by the editorial page editor dissenting from the Post’s endorsement of the Conservatives would have confused readers and embarrassed the paper.”

5. I don’t see public disagreement as confusing. I see it as honest. Readers, in my view, are adults & understand that adults can disagree. — Andrew Coyne (@acoyne) October 19, 2015

7. To be clear, the owners and managers of a newspaper have a perfect right to set the paper’s editorial line as they wish. — Andrew Coyne (@acoyne) October 19, 2015

9. Nobody has a God-given right to be published and the country will get along very well without me telling them how to vote. — Andrew Coyne (@acoyne) October 19, 2015

Coyne said he chose to resign but stay on as a columnist to preserve his editorial independence — and came out with a surprising endorsement for his local NDP candidate.

14. I think that’s all I need to say on the subject. If anyone’s still interested, I will be voting for the NDP candidate in my riding. — Andrew Coyne (@acoyne) October 19, 2015

15. The short-form reasoning: the Conservatives don’t deserve to be re-elected, and the Liberals don’t deserve a majority. — Andrew Coyne (@acoyne) October 19, 2015

That puts an end to speculation running rampant on social media since Friday over his future at the Post after the online news site Canadaland reported he had pushed back against Postmedia’s Conservative endorsement. Call it a last-minute election day troll.
