New era shortly — PC state the end of white van man? (10)
I believe the answer is:
pacesetter
'van man?' is the definition.
(someone at the front or 'van' of a race)
'new era shortly pc state the end of white' is the wordplay.
'new' indicates an anagram.
'shortly' means to remove the last letter.
'the end of' says to take the final letters.
The final letter of 'white' is 'e'.
'era' with its last letter taken away is 'er'.
'er'+'pc'+'state'+'e'='erpcstatee'
'erpcstatee' is an anagram of 'PACESETTER'.
(Other definitions for pacesetter that I've seen before include "early leader in race" , "temporary leader" , "Leading light in one's field, eg fashion, sport, arts" , "Runner" , "One who's performance gives the standard for others to reach" .)
