The striker departs Liverpool after more than a decade with his boyhood club, having joined the Academy ranks at the age of seven.
He progressed to represent the Reds’ U18s, U19s and U21s teams in recent seasons and was named on the bench for the Carabao Cup quarter-final tie at Aston Villa in December 2019.
Stewart recovered from a long-term ACL injury to fulfil a dream when he started for Jürgen Klopp’s senior Liverpool side against Derby County in the same competition last November.
The 20-year-old now takes a new step in his career by joining Preston on a permanent basis, with Reds defender Calvin Ramsay already at Deepdale on loan.
Everyone at Liverpool FC wishes Layton the very best of luck for the future.
