MP was told Birmingham Six evidence was ‘enhanced’

Evidence against the Birmingham Six was “enhanced”, a top-ranking police chief warned an MP years before their eventual release.

The chief constable told a Tory MP — who confided the revelation to an Irish diplomat, who in turn told the Irish Government — that police added “jam to the cake” to make the evidence stick.

In a courier-delivered letter, marked Secret and Personal, the diplomat alerted the Taoiseach’s office in Dublin about the claim in December 1987 — weeks before judges upheld convictions against the six innocent men.
