Derek McInnes has been confirmed as the new head coach of Heart of Midlothian.
The 53-year-old has signed a four-year contract at Tynecastle to replace Neil Critchley, who was sacked at the end of April.
McInnes led Kilmarnock to promotion to the William Hill Premiership at the first time of asking before consolidating the Ayrshire club in the top flight.
Killie finished in fourth place in 2023/24 and qualified for the UEFA Europa League and Conference League qualifiers before ending the 2024/25 campaign in ninth spot.
Having started his managerial career with St. Johnstone, McInnes is best known for his spell with Aberdeen where he took the Dons into Europe on seven occassions and won the 2014 Scottish League Cup.
In a statement, Kilmarnock confirmed the hunt for their new manager has begun with Alan Archibald and Paul Sheerin joining McInnes in Edinburgh.
