No, AB, it is not an offence in England and Wales.
The police have powers to arrest someone to prevent a breach of the peace. Occasionally the CPS brings a miscreant to court and ask that he be “bound over to keep the peace”. But no criminal offence is charged or conviction recorded in these circumstances.
This article (albeit from Wikipedia) explains the situation quite clearly:
http://en.wikipedia.o...i/Breach_of_the_peace
The relevant passage is how I understand the situation:
“The only immediate sanction that can be imposed by a court for breach of the peace is to bind over the offender to keep the peace: that is, justices of the peace can require a person to enter into a recognizance to keep the peace. Any punishment (in the sense of a loss of freedom or permanent financial penalty) takes the form of loss of the surety if the defendant fails to keep the peace or be of good behaviour during the period for which he is bound over. The binding over itself does not amount to a conviction (but any following behaviour causing loss of the surety might well result in conviction for an associated offence). A failure to enter into a recognizance may of itself lead to a person being committed to custody under s.115(3) Magistrates Court Act 1980.”
The interesting point is the last one which explains that a peron may be committed to custody for refusing to be bound over even though he may not have been charged or convicted of any offence.
The situation is different in Scotland.
