Indication of sorrow as holiday cancelled — blast! (4,1,5,3)
I believe the answer is:
tear a strip off
'blast' is the definition.
(both can mean to strongly criticise someone)
'indication of sorrow as holiday cancelled' is the wordplay.
'indication of sorrow' becomes 'tear' (as in crying tears).
'holiday' becomes 'trip' (I've seen this before).
'cancelled' becomes 'off' (similar in meaning).
'tear'+'as'+'trip'+'off'='TEAR A STRIP OFF'
(Other definitions for tear a strip off that I've seen before include "Criticise" , "what a seller of raffle tickets is seen to do?" , "Rebuke" , "discipline?" , "Reprimand (someone)" .)
