Just over 25 per cent of clues contain a redundant word that must be removed before solving. Then 10 answers (5 pairs) have to be modified before entry
4a Pledge internal security to be reviewed in regimental HQ
Think this might be one of the "10" as above .....grid entry is looking like topside??
31a Congested city backed in actual redevelopment of slums
possibly another of the 10 ... grid entry R??L possibly reel or real ?
I've not given word length in clue as I think these have to be modified ??
