Backed by Dame Esther and Dignity in Dying, it will run until July 5.
If the petition reaches 10,000 signatures, the Government will provide a written response.
If it passes 100,000 supporters, it will be considered for debate in Parliament.
Please add your voice to our call if you believe that dying people in the UK should have the option to end their lives with dignity, subject to strict eligibility criteria and safeguards.
