Right to protest
The right to peaceful protest is a vital part of democracy, and it has a long, distinguished history in the UK. Here?s some basic information about protests, as well as a few other ways in which you can make your voice heard.
Peaceful protests
Taking part in a demonstration, rally or protest is a high-profile way to take a stand on issues important to you.
Protests can make a real difference ? leading to changes in governmental policies and laws. Peaceful protests allow people to come together and stand up for what they believe in, and can be a very effective way of promoting change.
The Human Rights Act
The Human Rights Act protects freedom of expression and freedom of assembly ? these form the basis for your right to gather with others and protest.
The act forbids governments and other public bodies (including police) from violating these rights. However, it does allow for some limitations on these rights in order to prevent unrest, violence and crime, and for the protection of the rights and freedoms of others.
The police work to balance the right to protest with the right of other people to go about their lives safely and freely.

Organising a protest
Tell the police if you are organising a protest
The key message from police and local authorities to protesters is always ?let us know?.
Protests are most likely to avoid confrontation with local residents or workers, or the involvement of police, if organisers:
- notify the police in advance of their plans for the protest
- advise them of expected numbers
- apply for a permit if one is required or requested
If you are organising a march, you are legally required to notify the police six days in advance, or as soon as it is reasonably practical to do so.
If you are organising a protest rally that will not involve a march, you are not obliged to notify the police, but you may still want to let them know.
This courtesy allows local authorities to prepare for the gathering, to divert traffic if necessary to ensure the safety of the protesters, and to alert local residents to the disruption they?re likely to face."
