The 24-year-old spent the second half of last season on loan with U’s in League One, helping them to promotion to the Championship, and has now completed a permanent transfer to remain at the Kassam Stadium.

Cumming, who joined the Blues at the age of eight, previously spent time on loan at Stevenage, Gillingham, and MK Dons. He was named Player of the Year and Players' Player of the Year at the latter.

Good luck for the future, Jamie!
