BBC: Yanukovych and the tycoons
President Yanukovych is widely seen as living in symbiosis with Ukraine's tycoons. Initially that was largely true, but after becoming president in 2010 he quickly concentrated not only power but also wealth in the hands of his family - turning the big businessmen against him.
The surviving tycoons now see Yanukovych as the greatest threat to their survival, which has made most of them supporters of the European Association Agreement that the president shelved last month.
