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' says to put letters next to each other.
'time again' becomes 't' (abbreviation. I am not sure about the 'again' bit.).
'p'+'i'+'t'+'t'='PITT'
'on' acts as a 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" .)
