Breach of the peace is a common law offence, meaning it has been developed by the courts and does not have a specific basis in government statute
In England, there has not yet been anyone charged with a specific offence, although there have been reports of an arrest – and a barrister in London was threatened with arrest if he wrote “not my king” on a blank piece of paper
The Tory government’s act, which came into effect in April, gives police in England the right to impose conditions on protesters if noise generated by them may lead to alarm or distress for people in the area, according to
