The European Commission faces a censure motion in the European Parliament next week after right-wing, and far-right Eurosceptic lawmakers united to condemn the role its president, Jean-Claude Juncker, played in Luxembourg tax evasion schemes.

A lack of support for the censure motion from other parties, less than a month after the legislature endorsed the appointment of Juncker’s 28-strong executive team, makes it highly improbable that his critics will win the two-thirds majority required to force the Commission from office. Such an event would be unprecedented.

Parliament has no power to sanction individual members of the executive. An alliance of Eurosceptics, including Britain’s UK Independence Party, the French National Front and Italy’s 5-Star Movement gathered 76 signatures to meet the threshold of 10% of the 751-seat chamber to put the motion on the agenda.

The motion was tabled by the Europe of Freedom and Direct Democracy Group in the European Parliament, which is led by UKIP leader Nigel Farage.

It stated that Juncker, who was Luxembourg’s prime minister for two decades until a year ago, was directly responsible for tax policies which are now under investigation by the Commission for unfairly attracting multinational businesses.

Eurozone countries have had to slash spending and hike taxes to counter government debt crises in the past few years, heightening public resentment of schemes that help wealthy individuals and companies to pay less tax.

“A person who is responsible for the creation, the implementation, the governance and the monitoring of these aggressive tax avoidance policies does not have the credibility to serve the European citizens as President of the European Commission,” the motion read.

“The LuxLeaks scandal shows that Commission President Juncker in his political life has always acted to enrich his country behind its European partners, in defiance of the Union and the Community spirit he hopes to represent,” commented 5 Star Movement MEP Marco Zanni.

“This motion of censure means there must now be a debate on the behaviour of President Juncker and a vote to remove the entire European Commission,” added UKIP MEP Steven Woolfe.

Juncker has said he wants a level playing field in corporate taxation. The censure motion, brought by parties that oppose EU oversight over states, said “tax sovereignty” was vital for competition but Luxembourg’s policies were not fair competition.

Eurosceptics won a bigger voice in parliament at elections in May amid growing disillusionment with economic austerity and perceived failures of European Union administration. They have complained of a “grand coalition” of mainstream parties backing Juncker and trying to suppress minority views in parliament.

A previous attempt by the Parliament’s Leftist group GUE/NGL failed to obtain the required number of signatures. The MEPs said at the time they will not accept far-right MEPs who wish to join their initiative.
