A very up-to-date record about people who ruled Egypt (9)
I believe the answer is:
amenhotep
'who ruled egypt' is the definition.
(Amenhotep was a pharaoh of Egypt)
'a very up-to-date record about people' is the wordplay.
'very up-to-date' becomes 'hot' (hot can mean current or trendy).
'record' becomes 'EP' (abbreviation for extended play record).
'about' means one lot of letters go next to another.
'people' becomes 'men' (men are people).
'hot'+'ep'='hotep'
'hotep' after 'men' is 'menhotep'.
'a'+'menhotep'='AMENHOTEP'
(Other definitions for amenhotep that I've seen before include "Pharaoh" , "Egyptian leader" , "- IV changed his name to Akhnaten" .)
