Mr Paisley’s father, Ian Paisley, was a former Northern Ireland first minister who founded the DUP, now Northern Ireland’s largest unionist party, in 1971.
However, before his career in politics was his life in religion – he became a religious minister as a young man and went on to found the Free Presbyterian Church.
Along with fiery sermons, Ian Paisley became known for his opposition to Catholicism and the Pope.
To mark the death of Pope John XXIII in 1963, he said: “This Romish man of sin is now in hell.”
Mr Paisley also protested against Pope John Paul II in 1988, when the Roman Catholic leader was giving an address at the European Parliament.
He interrupted the address, saying: “I denounce you, antichrist. I refuse you as Christ’s enemy and antichrist with all your false doctrine.”
He was then forcibly removed from the chamber.
