Harry and Simon Maceachen prepare for liver transplant surgery

Harry Maceachen, who recently ran amok in the Breakfast studio, has had surgery to receive a part of his father's liver.

Four-year-old Harry was born with a rare liver disease and had a transplant on his first birthday, but needed another due to "a very rare mechanical failure."

Simon Maceachen became a living donor for his son when no suitable match was found on the organ donor register.

Tim Muffett caught up with the Maceachen family as they prepared for the surgery.
