Secure chair and refer to position politician's likely to hold on to (4,4)
I believe the answer is:
safe seat
'refer to position politician's likely to hold on to' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'secure chair' is the wordplay.
'secure' becomes 'safe' (similar in meaning).
'chair' becomes 'seat' (something to sit on).
'safe'+'seat'='SAFE SEAT'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for safe seat that I've seen before include "Constituency unlikely to be lost" , "Parliamentary constituency with a substantial majority for the incumbent" , "Constituency odds-on to be retained at an election" , "What the Uxbridge and South Ruislip constituency is for Boris" , "Constituency MP prefers" .)
