Who you ask and how you ask matter, as does why you are asking — the history of opinion polls shows they are as much about creating opinions as they are about recording them, writes socialist historian KEITH FLETT

THE labour and trade union movement has lost one of its most respected activists with the death of Ken Capstick, who for more than half-a-century was a tower of strength in the National Union of Mineworkers (NUM) and close friend and comrade to former NUM president Arthur Scargill.
Capstick, 84, died in Bulgaria where he was visiting his son David. He was born in the Yorkshire mining community of Hemsworth and trained as an electrician in the coalmining industry, becoming an activist in the NUM. He worked at Park Hill colliery in Wakefield. When Park Hill closed in 1982 he transferred to the huge Selby coalfield.
A decade earlier he was involved in the Battle of Saltley Gate, when engineering workers in the Midlands downed tools to reinforce striking miners picketing a coking depot, successfully closing it down.
