99% likely, is it the bedroom?

Maybe put a hit/miss vent on the lower part of the wall so that area will be ventilated
In some cavity walls it's well known for mortar dropping bridging the dpc, this will be when it's raining mostly
Any photo's of the outside?

A hit miss vent already exists, so putting a second vent beats the point as it would make the room extremely cold.
As for mortar dropping - yes it's a possiblity, but as you can see from the photo, the plaster is bone dry after scraping/clean the top layer, which means to me that the dpc has not been affected...or am i wrong?
I'll try to get some photos for the outside, but in the meantime, are there anymore suggestions? What about using a anti-condensation paint?

Are you still having problem with it even though the plaster is dry

Sorry mate, but i don't understand the reason for your question.
FYI, I still have the mouldy wall - condensation/damp issue and thats why i took off the wallpaper and scraped off the top layer of the plaster.
This was to see if there is penetrating damp or if the problem was just on the surface of the plaster.
After taking off 1mm of the top layer of the plaster, i found dry plaster underneath...surely this means no damp????
If that is the case, then it's only condensation that can cause this, in which case i need the solution to solving this problem.

You've just answered your own question
More ventilation!
If the moisture cannot get out then condensation problem, might be just the location of the ventilation, that's why I said put a small vent maybe in the wall just on top of the skirting board because that's where the condensation is ending up or just wait and see.
A dehumidifier will control it but can produce warm moisture back into the room!

Someone on here said you can put tin foil on the wall to establish weather its condensation or not, that aside you need to find out and eliminate were the moisture is coming from in the first place.
thanks catlad. Our house is an old victorian terrace, made in 1900. We do have a kitchen extension...similar to the image below, but without any french doors:-
This kitchen extension internally leads to the room where the damp/condensation is.
