Robinson and Carroll announced they are stepping down from the EDL amidst concerns over the dangers of far-right extremism. Their decision follows discussions with anti-extremist organisation Quilliam which helped to facilitate their departure.
Dr Feldman said: 'Robinson and Carroll are admitting the movement they created has grown out of control. Like Frankenstein’s monster, it has been attracting smaller more extreme far-right movements who have been attaching themselves to demonstrations and rallies.
'This has led to the growth of what we have called ‘tit for tat extremism’ with the so-called new far-right characterising all Muslims as potential jihadists and Islamist extremists reacting accordingly, for example, on 30 June 2012 when a jihadi Islamist gang plotted to blow up an EDL demonstration in Dewsbury.
'This has made things more tense for communities right up and down the country and has posed a threat to community cohesion which in turn has led to a strain on resources including policing and the criminal justice system.'
The departure of Robinson and Carroll, as well as a number of senior figures from the EDL, raises the prospect of the group falling apart entirely.
Professor Copsey said: 'It is not yet clear what will happen next but it will be difficult for the EDL to continue in the same way as before. We have been warning for a long time about the extremist views of the EDL and for those inside the group to be expressing the same concerns must be a positive step forward.
'However, it is important not to forget that the EDL has always been a loose organisation with a tendency to splinter. These splinter groups will see this development as an opportunity to jostle for advantage.' A recent report by the º£½ÇÖ±²¥ Centre for Fascist, Anti-Fascist and Post-Fascist Studies showed that almost three-quarters of anti-Muslim hate crimes reported to a monitoring organisation are taking place online – with the English Defence League highlighted as the far-right group implicated in the majority of internet attacks.
The report, based on data from Faith Matters’ Tell MAMA (Measuring Anti-Muslim Attacks), project also revealed a surge in anti-Muslim attacks since the murder of Drummer Lee Rigby in Woolwich, rising from an average of 1.5 reported incidents a day, to 6 to 7 reported incidents.
