Eilidh Barbour has more highlights of the 150th Open Championship from St Andrews as the world's best seek to make the cut on the famous and unforgiving Old Course.

Matt Fitzpatrick will be hoping his strong start to the season continues – he's vying to become the first Englishman to lift the Claret Jug since Sir Nick Faldo in 1992.
Andrew Cotter, Ned Michaels and Ken Brown provide commentary.
