Around a quarter of the UK's adult population have signed a petition to Parliament. It's one of the ways that UK residents can alert members of Parliament to concerns that matter to them and make their voices heard.

Petitions to the UK Parliament e-petition site ask for a change to the law or to policy. Since launching eight years ago, more than 30,000 petitions have been created, attracting more than 110 million signatures – and 350 of them have been debated by MPs.

Today, podcast host Catherine McKinnell MP, unwraps how the process works and ask how petitions can make a difference, through the experience of Andy Airey.

Andy is one third of ‘Three Dads Walking’ who petitioned Parliament to make suicide prevention a compulsory part of the school curriculum.

Andy's daughter Sophie took her own life in 2018, aged 29. He campaigns alongside Mike Palmer and Tim Owen, who lost their daughters, Beth and Emily, at the ages of 17 and 19.

They are joined by Nick Fletcher, the member of the Petitions Committee who opened the debate in the House of Commons. Nick is the Conservative Member of Parliament for Don Valley.

A Professor of Politics at the University of Leeds, Cristina Leston-Bandeira works on how Parliaments engage the public, particularly through petitions. She sets out why petitions are important and how the UK compares to other countries and legislatures.

Your host, for the final time in this series, is Catherine McKinnell, the Chair of the Petitions Committee at the House of Commons and Labour MP for Newcastle upon Tyne North.
