DUBAI (Reuters) - Iran's supreme leader has told former hardline president Mahmoud Ahmadinejad not to stand again in next year's elections, state media reported on Monday, effectively eliminating a major challenger to pragmatist incumbent Hassan Rouhani.

Ahmadinejad had not announced any plans to run in the vote scheduled for May, but has made several speeches in recent months, prompting speculation of a political comeback.
