Police are struggling to hold back EDL marchers who are trying to push through the cordon.
Members of the English Defence League are marching to Downing Street this afternoon. At the same time, a counter demonstration is also being held by Unite Against Fascism.
EDL supporters are becoming more animated as they gear up to march from Trafalgar Square to Downing Street. Two EDL supporters told me they are marching against extremist elements of Islam.
