The garden of much-loved England (4)
I believe the answer is:
eden
'the garden' is the definition.
(Garden of Eden in the Bible)
'of much-loved england' is the wordplay.
'of' indicates the answer is hidden within the clue.
'EDEN' can be found hidden inside 'much loved england'.
(Other definitions for eden that I've seen before include "prime minister in the past" , "Leading 11 [CONSERVATIVE]" , "Former British PM - unspoilt paradise" , "Unspoiled paradise" , "Early garden - Cornish project" .)
