There has been recent legislation, some of it controversial, and some of it might be relevant to your event.

Racial and Religious Hatred Act

Parliament approved a bill on 31 January 2006 that made it a criminal offence to use threatening words or behaviour with the intention of stirring up hatred against any group of people defined by their religious beliefs or lack of religious beliefs.

Hatred is a strong term that goes beyond simply causing offence or hostility. Hate crime is any criminal offence committed against a person or property that is motivated by an offender's hatred of someone because of their:

• race, colour, ethnic origin, nationality or national origins
• religion
• gender or gender identity
• sexual orientation
• disability

Hate crime can take many forms including:

• physical attacks such as physical assault, damage to property, offensive graffiti, neighbour disputes and arson
• threat of attack including offensive letters, abusive or obscene telephone calls, groups hanging around to intimidate and unfounded, malicious complaints
• verbal abuse or insults - offensive leaflets and posters, abusive gestures, dumping of rubbish outside homes or through letterboxes, and bullying at school or in the workplace

The Home Office definition of a hate crime:

Any incident, which constitutes a criminal offence, which is perceived by the victim or any other person as being motivated by prejudice or hate.

The Race Relations Act 1976

1. Racial discrimination.

(1) A person discriminates against another in any circumstances relevant for the purposes of any provision of this Act

(a) on racial grounds he treats that other less favourably than he treats or would treat other persons; or

(b) he applies to that other a requirement or condition which he applies or would apply equally to persons not of the same racial group as that other, but

(i) which is such that the proportion of persons of the same racial group as that other who can comply with it is considerably smaller than the proportion of persons not of that racial group who can comply with it; and

(ii) which he cannot show to be justifiable irrespective of the colour, race, nationality or ethnic or national origins of the person to whom it is applied; and

(iii) which is to the detriment of that other because he cannot comply with it.

(2) It is hereby declared that, for the purposes of this Act, segregating a person from other persons on racial grounds is treating him less favourably than they are treated.

The Terrorism Act 2006 includes four main areas of consideration:

Acts Preparatory to Terrorism
This aims to capture those planning serious acts of terrorism.

Encouragement to Terrorism
This makes it a criminal offence to directly or indirectly incite or encourage others to commit acts of terrorism. This will include the glorification of terrorism, where this may be understood as encouraging the emulation of terrorism.

Dissemination of Terrorist Publications
This will cover the sale, loan, or other dissemination of terrorist publications. This will include those publications that encourage terrorism, and those that provide assistance to terrorists.

Terrorist training offences
This makes sure that anyone who gives or receives training in terrorist techniques can be prosecuted. The Act also criminalises attendance at a place of terrorist training. (From Home Office website)
