Cyril Smith's "extremely dominant" personality made his victims reluctant to come forward with allegations, according to a police report accusing the former Liberal MP of committing numerous indecent assaults on teenage boys.
The assaults allegedly took place in a residential hostel whose establishment Smith had been the "prime motivator" behind.
The redacted document says Smith enjoyed great prestige in his home town of Rochdale, where he was "dominant in council affairs" and had "favourable publicity" from the local newspaper.
It also says the 29-stone politician's "sheer physical bulk" was one of the factors that "overawed" his young victims.
