Loyden was Member of Parliament (MP) for Liverpool Garston from February 1974 until he lost the seat to the Conservatives in May 1979.
He was born in 1923 into a large, working-class family living in Portland Street off Vauxhall Road, Liverpool.
His maiden speech focused on the plight of the unemployed and the poor housing conditions that still existed in the City of Liverpool.
He was involved in the seamen's strike of 1966, despite Harold Wilson’s denigration of the strikers as a "tightly knit group of politically motivated men".
In 1974 Loyden was elected MP for the Garston area of Liverpool, a former traditional Tory seat.
