Fresh allegations have emerged surrounding illicit activity conducted by the now defunct News of the World with claims that the paper hired a private detective to put a former Metropolitan Police Commissioner under surveillance.
The claims were levelled by Jonathan Rees, co-founder of Southern Investigations, who said that Lord Stevens was monitored by the tabloid after hearing a rumour that he was using a police aircraft to fly to Northumberland to see a mistress.
Stevens regularly flew the light plane, which he co-owned.
Rees alleges that Stevens was monitored by the paper to dig any dirt they could on him, a bid to exert influence on the former Police head.
Speaking to the independent voices website Rees said: “We were given instructions and an allegation that he was using a Met police plane from Biggin Hill to see his mistress in Northumbria.
“Now we did organise a surveillance team and we had teams in Northumbria and here, but he never showed up so whether the allegation was true or not, who knows?"
A spokesman for Lord Stevens denied that he had a mistress adding that he had never flown to Northumbria.
