CARACAS (Reuters) – Venezuelan opposition leader Henrique Capriles challenged President Nicolas Maduro’s narrow election victory before the Supreme Court yesterday, prolonging what appears to be a futile effort to overturn last month’s vote. Capriles refused to accept the results of the April 14 vote for a successor to late socialist leader Hugo Chavez, and called on supporters to take the streets. That led to unruly demonstrations in which the government says nine people died. Few expect Capriles to win a favourable ruling from the court, which the opposition says is controlled by the ruling Socialist Party. He may also go to international tribunals, though most countries have recognised Maduro’s win.
