Angry voters threatened to abandon the Labour Party this week following the Peter Mandelson passports fiasco.
Almost half the population would change the way they voted on the basis of this or similar scandals, according to NOP Solutions research for PRWeek.
The survey asked voters how much such scandals would affect their vote.
Twenty-one per cent said 'a lot,' a further 21 per cent said 'a little,' while the final 58 per cent said 'not at all'. Voters in the 18 to 35 age group are slightly more likely to change their votes in the wake of recent events than older citizens.
Labour should be worried by the research's other findings. A three-to-two majority think the media outcry over Mandelson's resignation has damaged the party more than the politician. The over-55s are most likely to exonerate the disgraced ex-Ulster secretary, by 63 to 37 per cent, as against 55 to 45 for those in other age groups.
