We thought that we were going insane, we couldn't understand what was happening to us, what had happened to my son. INQUEST has supported, enabled, educated and empowered and restored our faith in justice. We were given back our voice. – Family member
As well as working with your own MP you can try to influence others in parliament in a number of different ways;
MPs on a Committee decide what issues they are concerned about and hold inquiries into these, they may ask for written and/or oral evidence from interested organisations and members of the public. Anyone can write to the Committee to tell them about their experiences if they are relevant to their current inquiries. The results of these inquiries are public. Committees will make findings and recommendations in their reports and many require a response from the government.
A full list of the Committees and links to what they do and what they are currently examining and deadlines for sending written evidence can be found on the parliament website: http://www.parliament.uk/business/committees/committees-a-z.
