Greek Prime Minister Alexis Tsipras pleaded in the European Parliament on Wednesday for a fair deal to keep his country in the euro zone, acknowledging Greece’s own responsibility for its plight, after EU leaders gave him five days to come up with reforms. Speaking hours after euro zone peers, at another emergency summit in Brussels, set Greece a deadline of the end of the week to come up with convincing reform proposals, Tsipras said Greeks had no choice but to demand a way out of “this impasse”.
