The world governing body is the WBF. In Europe, Bridge is coordinated by the European Bridge League (EBL). The World Mind Sports Games (which includes Bridge) is coordinated by the International Mind Sports Association.
Bridge is now devolved to the EBU and equivalent organisations in Scotland and Wales. Bridge Great Britain is responsible for the series of home internationals (between England, Scotland, Wales, Ireland, and Northern Ireland) and the Gold Cup (a major knock-out teams competition like the FA Cup of Bridge).
