Old prime minister takes princess round country (8)
I believe the answer is:
disraeli
'old prime minister' is the definition.
The definition suggests a singular noun which matches the answer.
'princess round country' is the wordplay.
'princess' becomes 'di' (Princess Diana).
'round' indicates putting letters inside.
'country' becomes 'israel' (Israel is an example).
'di' placed around 'israel' is 'DISRAELI'.
'takes' is the link.
Can you help me to learn more?
(Other definitions for disraeli that I've seen before include "Benjamin -, nineteenth century PM" , "Victorian prime minister" , "Ali dries out the old British prime minister" , "Queen Victoria's favourite prime minister, d. 1881" , "Raise lid on this old British prime minister" .)
