Whatever happened to Hattie Jacque's lover John Schofield?

The brilliant Britsh comedienne who was married to John Le Mesurier had a car salesman/chauffeur lover for years who broke her heart. Some people think that she died of grief when her caddish lover broke it off when they were in Italy for a work project. I saw somewhere that he ran off with an Italian heiress.

I also heard that when Hattie's health broke down with the stress of the breakup that he walked into her hospital room and threw a gold locket that she'd given him on to her bed then just walked out again.

Does anyone know anymore about him?

Where did he go?

When did he die?
