You good people are always very helpful. 
can you please recommend what I could do to fix this mess? 
 

it was covered up by skirting board

 

its a harmony timber frame construction 

if that helps 

 

The vapour barrier is missing in this part but its in the rest of the wall

Thanks for the reply
thats what I was thinking to use but I would like to prevent condensation hitting the wall plate and studs. Will this prevent that from happening? 
I can’t understand why someone would butcher the wall like this removing  vcl and insulation etc
