Ms Rudd, maybe, chases companion in the bedroom (7)
I believe the answer is:
chamber
'bedroom' is the definition.
(I know that bedroom can be written as chamber)
'ms rudd maybe chases companion' is the wordplay.
I cannot quite understand how this works, but
'companion' could be 'cha' (Companion of Honour) and 'cha' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for chamber that I've seen before include "Official room" , "Room where a judge transacts business" , "A house of parliament" , "posh room" , "Judicial assembly - room" .)
