Booth is a former London Irish director of rugby, while he also spent seven years as Bath first-team coach and had an assistant role with Harlequins.

He started at the Ospreys in the summer of 2020 when the Swansea-based team were in disarray and helped transform their fortunes.

The 2023-24 season was arguably his most successful, Ospreys reaching the URC play-offs by finishing in the top eight and recording a first European play-off victory on the way to the Challenge Cup quarter-finals.

During the previous season, Booth oversaw a Champions Cup double over then French champions Montpellier before Ospreys were defeated by Saracens in the last 16.

Booth gave young players a chance as he had to cope during his time in charge with the loss of high-profile names like Alun Wyn Jones, Rhys Webb, George North, Tomas Francis, Nicky Smith, Gareth Anscombe and Alex Cuthbert.

He enjoyed a 70% success rate in Welsh derbies as he turned Ospreys into the best side in Wales for two of his four full seasons in charge.

Wales captains Jac Morgan and Dewi Lake flourished under Booth during his time with the Welsh region.
