William Collum has been confirmed as the referee for the William Hill Scottish Cup final on May 25. 

The experienced official adds the showpiece fixture between Heart of Midlothian and Celtic to what has been a busy season for the Scotsman. 

Collum has been in charge of three Scottish Cup fixtures this term, including Hearts Fourth Round win over Livingston and Celtic's Sixth Round victory over Hibernian.

And it won't be his first fixture in 2018/19 between the Jambos and the Hoops, after he took charge of the League Cup semi-final back in October at Murrayfield. 

It won't be Collum's first Scottish Cup final, with his previous involvement as referee coming back in 2015 between Inverness CT and Falkirk. He was also in charge of Celtic's 3-0 victory in the Cup final in 2013, when the Glaswegian side defeated Hearts' city rivals Hibernian 3-0.

Collum will be assisted at Hampden Park by Alan Mulvanny and Ralph Gordon, with Don Robertson on Fourth Official duties. 

Kevin Clancy and Bobby Madden will be the Additional Assistant Referee's on the day as Hearts and Celtic go head-to-head for the final piece of silverware in the domestic calendar this season.
