Controversial plans to reform the Davis Cup have been given the go-ahead.
A two-thirds majority among 140 nations was needed at the International Tennis Federation (ITF)'s annual general meeting.
The tournament will now be turned into a season-ending 18-team event - as part of a 25-year £2.15bn plan - to start in 2019.
The Lawn Tennis Association, Britain's governing body, opposed the proposals.
The LTA said it remains concerned about scheduling, financing and the division between member nations.
