2014 Winter Olympics held in Sochi, Russia

Host nation Russia finished on top of the medal table as the 22nd Winter Olympics came to a close in Sochi after 17 days of competition.

The Games cost ￡30bn, making Sochi the most expensive Olympics ever, and featured a record 2,800 athletes from 88 countries, with 12 new events added to attract young audiences.

But there were also six failed drugs tests - five more than in the 2010 Vancouver Games - as the most extensive anti-doping program in Winter Olympics history saw a record 2,453 tests carried out.
