Wembley content with minute sign (6)
I believe the answer is:
emblem
'sign' is the definition.
(I know that emblem is a type of symbol)
'wembley content with minute' is the wordplay.
'content' indicates the central letters.
'with' means one lot of letters go next to another.
'minute' becomes 'm' (abbreviation).
The central letters of 'wembley' are 'emble'.
'emble'+'m'='EMBLEM'
(Other definitions for emblem that I've seen before include "Symbol; heraldic device" , "Badge, token" , "Device, badge or symbol" , "Symbolic device or badge" , "Logo" .)
