Delegates at the annual general meeting of the SRU were asked to choose between Jack, Peter Brown and Jim Stevenson, who proved almost inseparable after the first round of voting.

Jack, proposed for the role by Leith Academicals, received 57 votes, with Brown and Stevenson gaining 56 each, and Brown opted to step aside to allow for a head-to-head poll between the two other candidates.

With Brown out of contention, delegates voted in favour of Jack by a 91-75 margin, meaning the vice-chairman of the Scottish Rugby Council moves into the higher office for the next two years.

Chief executive Gordon McKie also confirmed the SRU would pay 100% of club accident insurance premiums from the start of the new season, predicting it would help clubs save "a six-figure sum".
