The European Parliament took a vote of confidence today on the newly appointed Commission of Jean Claude Juncker. The vote, triggered by the Luxleaks tax avoidance revelations, was called by the EFDD group in the Parliament of which Ukip makes up a majority. The vote failed by 461 votes to 101 and Nigel Farage didn’t even turn up.

The Luxleaks scandal is very worrying – under Juncker's watch as Prime Minister, it looks like Luxembourg arranged at least 300 secret deals with multi-national companies to help them avoid tax – and he must be held to account for this. But Ukip’s moves should be seen for what they really are: another futile heckling tactic which is more about grabbing the headlines than real action

May 22 2014, the day that Ukip won the European elections, I’m afraid to say we made the wrong choice as Ukip are beginning to prove time and time again their insignificance in Europe. I understand the frustration with the traditional three main parties who offer little more than different shades of business as usual, but a vote for Ukip is a vote for empty gesture politics.

As revealed earlier this year, Ukip MEPs are failing to engage with the political process as usually they don’t bother to show up and, when they do, they can often be found heckling and shouting abuse across the chamber.

This may not be such a scandal if they weren't gaining such huge benefits from being our main representation in Europe – but the scary part is that they receive millions of pounds each year in salaries and funding for their group in the parliament. That was why Ukip were so panicked last month when their EFDD group nearly collapsed; they would have lost an estimated £1m. They did manage to save their group in the end – but only by welcoming an MEP into their group who has been labelled a racist and a holocaust denier.

It is becoming increasingly clear that Ukip MEPs aren’t the right people to represent our interests in Europe. On most key issues you would be hard pushed to quote any Ukip achievements. For example, 80 per cent of environmental legislation in the UK comes from the EU – most of it providing many benefits to the environment, but more often than not Ukip MEPs have opposed such moves. Many of our workplace and social protections also come from Europe, again, no thanks to work done by Ukip.

The vote of confidence in team Juncker may be a successful attempt by Ukip to position themselves as the anti-establishment party in the media, but as Owen Jones pointed out this week, this couldn’t be further from the truth. Ukip are the embodiment of corporate interests and they really don’t care about cracking down on tax avoidance.

Are Ukip prepared to take on the powerful vested interests in the City? And are they prepared to consider supporting Green proposals on tackling the scourge of tax evasion including enforcement of existing tax legislation and increased transparency including a minimum rate for corporation tax.

Based on their behaviour so far in Europe, I wouldn’t hold my breath in waiting for them.

On these issues, my Green colleagues and I have been leading the way. And in response to the Luxleaks issue we have developed a proposal to take concrete action. We are calling for the establishment of a committee to carry out a robust inquiry into tax evasion and dumping, not just related to Juncker, but across the EU and beyond.

Sacking the entire Commission irrespective of each individuals’ involvement in the scandal may hit the headlines, but it would do nothing to tackle the deeper issue of tax avoidance which has plagued the EU for far too long.
