The highest mountain in England (7,4)
I believe the answer is:
scafell pike
'the highest mountain in england' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scafell pike that I've seen before include "England's highest mountain" , "High spot in England" , "Highest English mountain" , "Highest peak in England" , "Cumbrian mountain" .)
