ATHENS/BRUSSELS (Reuters) – Greek Prime Minister Alexis Tsipras comfortably won a confidence vote on his plan to cancel a deeply unpopular bailout program and challenge European leaders as both sides prepare for a showdown at meetings in Brussels this week. In a rousing speech to parliament, Tsipras hailed the decisive role “little Greece” was playing in reshaping Europe and promised Athens would not cave in to demands it extend its international bailout “no matter how much” German Finance Minister Wolfang Schaeuble asked for it.
