European Commission chief Jose Manuel Barroso said he did not expect a "miracle" at the G20 summit this weekend but rather first steps to tackle the most dire problems facing the global economy.
"We cannot expect a miracle from this summit, which was Europe's idea, but will rather see the beginning of a process that will create a finished programme in 100 days," he said an interview with the German daily Sueddeutsche Zeitung published Friday. "This summit must not fail."
Barroso said that did not mean that concrete decisions would not be taken at the Washington meeting.
"For example we need to give the International Monetary Fund more power to act and achieve our main goal of imposing effective regulations on every relevant financial institution -- around the glob him have told prosecutors that they were beaten both in police custody and in prison.
European Union officials and Turkish human rights activists charge that cases of torture have begun to rise again in Turkey in recent years after a notable decline in the early 2000s.
Torture and maltreatment by the security forces is a major problem in Turkey's human rights record, followed closely by the EU, which the country is seeking to join.

Critics say that despite the government's policy of "zero tolerance to torture," accused officers are not properly investigated and the few who are eventually indicted are charged with abusing power rather than directly with torture.
