Support for the party has increased in the last month, a survey for The Daily Telegraph indicated.

The findings will lead to accusations that the BBC’s decision to invite the far-Right MEP on to its flagship current affairs programme may have backfired by giving him a national platform.

The YouGov poll was taken hours after Mr Griffin’s appearance on Thursday, before which anti-fascist protesters rioted outside BBC Television Centre in London.

The survey found that 22 per cent of voters would “seriously consider” voting for the BNP in a future local, general or European election. This included four per cent who said they would “definitely” consider voting for the party, three per cent who would “probably” consider it, and 15 per cent who said they were “possible” BNP voters.

Two-thirds said they would not consider voting for the party “under any circumstances” with the rest unsure.

Mr Griffin’s performance, during which he was challenged about his views on the Holocaust, immigration, Islam and homosexuality, has divided the political establishment. Some senior figures criticised the BBC for inviting him on to the programme.

David Lammy, the Higher Education Minister and one of the first black men to serve in a British government, gave warning of a potential rise in racist and anti-Semitic attacks, saying he was “very worried about the days which will follow”.

More than half of those questioned said they agreed with the BNP, or thought that it “had a point” in wishing to “speak up for the interests of the indigenous, white British people … which successive governments have done far too little to protect.”

The Times:

Groups of youths, in ski masks and motorcycle helmets, threw bottles and set off fireworks in front of riot police, who used kettling tactics to contain a crowd of up to 2,000 outside Harrow central mosque. Seven people were arrested for possession of offensive weapons including a hammer, chisel and a bottle of bleach. Another man was arrested “to prevent a breach of the peace”, police said.

Hundreds of Muslim youths and anti-fascist campaigners gathered to confront a fringe right-wing group calling itself Stop Islamification of Europe (SIOE). The group had threatened to hold a rally at the site, where a new five-storey mosque is under construction, but organisers said that they had called off the march at the request of police.

Despite pleas by imams for the crowds to go home, the streets remained packed for several hours. About 20 anti-Islamic protesters, some wearing football jerseys, attempted to enter the area but were blocked by some of the 500 police.
