Tantrum from tense European politician her husband ignored (6)
I believe the answer is:
temper
'tantrum' is the definition.
(I've seen this before)
'tense european politician her husband ignored' is the wordplay.
'tense' becomes 't' (grammatical abbreviation).
'european' becomes 'e' (abbreviation e.g. EU).
'politician' becomes 'MP' (Member of Parliament).
'husband' becomes 'h' (abbreviation).
'ignored' indicates named letters should be taken away.
'her' with 'h' taken away is 'er'.
't'+'e'+'mp'+'er'='TEMPER'
'from' is the link.
(Other definitions for temper that I've seen before include "Toughen with anger" , "Lose it and lose control" , "Moderate - anger" , "Moderate or soften the effects of" , "Bad humour" .)
