...will force him to step down (temporarily?) as NDP party leader? Apparently not:
Karl Belanger, Layton’s press secretary, said in an e-mail to Canwest News Service that Layton is not stepping down. He also said he was not running for Toronto mayor.
Well, this seems to rule out a serious health issue. Thank goodness for that.
PS: Word on twitter is he will leave his leaadership duties for "several months".
