Conservative sporting dodgy hairstyle wildly funny (10)
I believe the answer is:
hysterical
'wildly funny' is the definition.
(I've seen this before)
'conservative sporting dodgy hairstyle' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'sporting' indicates putting letters inside (inserted letters wear or 'sport' others).
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'hairstyle' anagrammed gives 'hysterial'.
'c' inserted within 'hysterial' is 'HYSTERICAL'.
(Other definitions for hysterical that I've seen before include "Frenzied" , "Over-emotional" , "overwrought" , "Extremely funny" , "Violently emotional" .)
