IMF calls for unity ahead of G20

---

The head of the International Monetary Fund (IMF) has stressed the need for unity among world leaders at the G20 meeting in London next week, reports BBC.
"It is absolutely necessary for leaders to find agreement," said IMF managing director Dominique Strauss-Kahn.
The UN has also called for urgent action at the G20 to prevent the financial crisis developing into a "catastrophe for human development".
There has been discord among leaders about how best to tackle the crisis.
"If there is a big clash at this [G20 meeting] on any topic among leaders it will not be good for confidence," Mr Strauss-Kahn said.
He expressed satisfaction that governments had acted according to recommendations from the IMF.
"What has been announced in terms of fiscal stimulus is broadly in line with the 2% of global stimulus that we were asking for."
World leaders will meet next week in London to discuss measures to tackle the downturn. See our in-depth guide to the G20 summit.
The G20 countries are Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom, the US and the EU.
Governments should "make sure that, if needed, more can be done in the course of 2010."
Mr Strauss-Kahn also said that other central banks might follow the lead of the US Federal Reserve and the Bank of England in pumping money directly into the economy.
There has been some disagreement between world leaders about the best way to stimulate economic growth.
In the US and UK, President Barack Obama and Prime Minister Gordon Brown have been in favour of injecting massive amounts of government money into their economies.
