The final round of The Open Championship is underway, the last 18 holes of major championship golf left this year.

Any change to The Open's final round timings, to avoid a clash with the World Cup final should England get there, will be made in "the next 48 hours" and be "subtle" says R&A chief Mark Darbon.

Live radio commentary and text updates of the final round at Royal Birkdale as the champion golfer of the year is decided.
