Is the other side of the wall interior or exterior? and whats that thing in the corner?

Check the exterior wall for height of dpc/bridging of dpc eg. soil piled up against the wall, faulty guttering.
And leaking lead pipe in wall.

ok i took some more pictures
the damp on the inside wall gets worse when it rains, so i guess the idea of damp course fault is out???
the drain outside was blocked this morning untill i unblocked it.
please take a look at photos.
best regards graham

The pattern of the circular damp spots is indicative of penetrating moisture moving across a joint in the wall at each location
It is getting in somewhere behind the render
Similar situation for the corner damp
Tap the render to see if it is hollow, otherwise you need to investigate to the sides and above externally

This looks like classic condensation to me.
We could probably rule out a leaking pipe as the dampness seems, according to the photos , to be at different locations.
DPC being bridged ( if one is present) is also a possibility.
Moisture ingress could also be the cause ie water penetrating the external wall.
The outside wall and the fact that we are talking about a kitchen, kind of points to the strong possibility of condensation.
To cut this down the kitchen would need to be kept warm and an exhaust fan running when cooking.
Also opening a window during / after cooking if windows are steaming up .
Its not possible to diagnose from the photos but I hope I have given you some idea what to look for.
Good luck
I was busy typing this when your latest post came where you say it gets worse when it rains. This points at moisture ingress being the favourite especially if there is no cavity and you have a solid wall. Of course even when there is a double brick wall if the ties have not been properly fixed it is possible for water to travel from the outer leaf to the inner.
