Declaring his retirement during his 80th birthday celebration in front of his family, friends and dignitaries from overseas and within the country, Sir Michael said 'it is time' for him to sit and see his baby country grow.
"So many challenges have come on me but I didn't give up. I stood up for this beautiful nation."
He thanked his beautiful wife Lady Veronica for standing beside him and supporting him during his political challenges.
Sir Michael served this country for 48 years, the longest in the Commonwealth countries.
He turned 80 yesterday.
