Yes, EDL leader Stephen Lennon has announced on Twitter that he has quit the British Freedom party. According to the BFP, "Tommy has recognised that his heart and strengths lie within the Street Protest Movements".
It is difficult to understand this decision, what with cousin Kev being on the point of getting elected Police and Crime Commissioner for Bedfordshire on the BFP ticket. Still, the EDL itself is about to recruit another 7 million members, so perhaps Stephen felt he would have his work cut out dealing with that.
