Bill-by-bill: Guide to MPs' private members' bills

Twenty MPs have won the right to bring in their own parliamentary bill on the issues that most concern them - from preserving the Antarctic to blocking prisoners' mobile phones. The BBC's Justin Parkinson looks at the full list and details the aim of each bill.

Stuart Andrew, Conservative	Prisons Property Bill	Change law so items smuggled in to prisons, such as mobile phones and weapons, which are confiscated, do not have to be returned to inmates on their release.
