dead centre

'cemetery?' is the definition.
(I've seen this before)

'slap bang in the middle' is the wordplay.
'slap bang in' becomes 'dead' (I can't justify this - if you can you should believe this answer much more).
'the middle' becomes 'centre' ('centre' can be a synonym of 'middle').
'dead'+'centre'='DEAD-CENTRE'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for dead centre that I've seen before include "bullseye" , "Smack in the middle" , "cemetery?" , "Right in the middle" , "heart" .)

I've seen this clue in The Telegraph.
