There was plenty about John Prescott Senior - consensual but inappropriate affair with civil servant
BUT
Labour were in government then
Government scandals will always get miles more publicity than those of Opposition parties - rightly so.
And there are harassment allegations against about 35 Tory ministers and MPs
Much more important than an aide / dogsbody
(btw, in my 61 years, I've never once voted Labour - I look at the individual candidate and Labour only offered me plonkers)
