Oh, please, that's a rubbish argument. They want to make a principled stand? Fine. You want to make a principled stand and donate the money in its entirety to a charity, or even to your own party? Fine.
If people actually fall for the 'I am taking this £100K plus a year and putting it safely in my bank account because I see it as taking a principled stand to highlight the hypocrisy of the system' then god help us all. But UKIP don't make a song and dance about this point of 'principle'. If there's any mention of it on their website, of their candidates' websites, it's well hidden.
The fact is that most people aren't even aware they do this. They vote for anti-immigration and anti-EU rhetoric that resonates with people who are scared, and for a man who affects to be a man of the people with his pint, his fag and his Borisesque affectations.
Paul Nuttall's MEP website claims:
'Over the next five years, he is committed to working tirelessly on behalf of those who elected him into office. As well as defending the UK’s interests in the European Parliament, Paul will campaign in Britain so UKIP can make a breakthrough at Westminster.'
Strangely he doesn't highlight that he plans to show up to few votes, but still claim his allowances, salary and pension. It's not highlighted in their candidate announcement press releases, either.
