Peers at the other house (5)
I believe the answer is:
This might be a double definition.
'peers' is the first definition.
(I've seen this in another clue)
'the other house' is the second definition.
'lords' can be an answer for 'house' (I've seen this before). I am not sure about the 'the other' bit.
'at' is the link.
Can you help me to learn more?
(Other definitions for lords that I've seen before include "Titled peers of the realm" , "masters" , "MCC HQ" , "Field" , "Headquarters of the MCC" .)
