Out of the two, Ronnie was seen as the most volatile - openly homosexual in a time when homosexuality was still a criminal offence, he also suffered from mental health problems.
In 1964, an exposé in the Sunday Mirror linked Conservative politician Robert Boothby and Ronnie with questions about a homosexual relationship and, although nobody was actually named, the tabloid came under enormous pressure to retract the story from the Krays, Boothby and, surprisingly Labour Party leader Harold Wilson. In fact, both the Conservative and Labour parties seemed more and more hesitant to press for police action against the Krays over the following years.
