McGuigan, who became World Featherweight Champion in 1985, shared many highs and lows in the jungle.
One moment which touched the hearts of many viewers was an emotional conversation in which he opened up about the death of his daughter.
McGuigan told his jungle campmates about how she originally recovered from leukaemia as a child after two years of treatment.
Actress Danika McGuigan died five weeks after being diagnosed with bowel cancer in 2019, aged 33.
During his time in the jungle, McGuigan took part in two challenges.
We was left frustrated in the coffin challenge as he was unable to gain stars for camp after not being able to see the number to unlock the codes for the padlocks while surrounded by snakes.
However, there was redemption as he gained 10 out of 11 stars in the ‘spiralling out of control challenge’.
McGuigan spoke highly of all his campmates but made no secret his favourite to win.
He found a close knit friendship with Danny Jones and told hosts, Ant and Dec, “Danny boy will win”.
