Old prime minister on Page 1 time and time again (4)
I believe the answer is:
pitt
'old prime minister' is the definition.
(William Pitt the Younger or William Pitt the Elder)
'page 1 time and time again' is the wordplay.
'page' becomes 'p'.
't' becomes 'I' (Roman numeral).
'time' becomes 't' (abbreviation).
'and' is a charade indicator (letters next to each other).
'time again' becomes 't' (abbreviation. I am not sure about the 'again' bit.).
'p'+'i'+'t'+'t'='PITT'
'on' is the link.
Can you help me to learn more?
(Other definitions for pitt that I've seen before include "a name in politics once" , "Brad --, US actor" , "Former British PM" , "old politician" , "Elder and Younger PMs" .)
