Roger in Sheffield - if you arfe sure that is happening, I'd suggest a letter addressed to the MP addressed as Personal, with a covering letter complaining about the secretary. That would have to get through. (Though in practice I wopuld suspoect that if the secretary is stopping letters getting through it is beacsue she or he has been asked to do so by the MP.

Keeping tracks on all these PEL threads going in parallel is getting tricky. I think some housework is required to simplify things.
