Berlin - The German parliament on Thursday slapped a 2.2 million euro (2.8 million dollars) fine on the far-right National Democratic Party of Germany (NPD) for accounting irregularities.

The party failed to list correctly its assets and funding it received from the state in its 2007 statement of accounts, an official announcement said.

According to the rules governing Germany's political parties, the fine is double the amount of the erroneous declaration.

The total sum involved is 2.5 million euros, but the party has made an advance payment of 304,000 euros. It was ordered to pay the remainder by May 1.

Political parties in Germany receive funding from the state to cover their election expenses, provided they receive a certain number of votes.

The NPD is not represented in the federal parliament in Berlin but has seats in two of Germany's 16 state parliaments.

The anti-foreigner NPD has been classed as "a threat to constitutional order" by Germany's domestic intelligence service.

An attempt to ban the party was thrown out by the country's constitutional court in 2003.

Earlier this week a far-right youth movement with links to the party was banned by Germany's interior ministry banned for spreading Nazi propaganda. (dpa)
