The Greens look like being the main beneficiaries of any anti-sleaze protest vote: latest polls suggest support for the Green Party is up, whilst that for UKIP and the BNP is down.
The reason is contained within a YouGov poll to be published later today. 2,000 people were asked to name the three parties whose candidates they thought were least trustworthy.
The Greens topped the poll - just five per cent of respondents thought Green Party candidates were more likely to put their own interests above those of the country.
Labour candidates were the leasst trusted: almost half of all respondents (45%) thought they were likely to put their own interests first.
The Conservatives fared almost as badly, with 40% naming them. Next were the BNP, the LibDems and UKIP on 20%, 16% and 15% respectively.
The new poll was released in the same week that campaign group Open Democracy rated the Green Party's leader Caroline Lucas as the joint best British MEP on accountability, transparency and reform.
The bottom nine places in the Open Democracy survey were occupied by four Conservatives and five UKIP MEPs - with the tenth-worst British MEP slot being held jointly by UKIP leader Nigel Farage and an MEP each from Labour, the Conservatives and the LibDems.
