Tsipras calls Syriza party vote on bailout

``Greece's Prime Minister Alexis Tsipras has thrown down a challenge to his critics by calling a "referendum" of Syriza party members on Greece's latest bailout agreement, saying his government had made "difficult choices" to protect the country from bankruptcy. Addressing the party's 200 strong central committee at a specially called meeting on Thursday, he proposed a Yes-or-No vote on the €86bn bailout to be held on Sunday."
