David Cameron goes to Brussels later this week to meet other EU leaders, as he tries to secure a new deal for the UK ahead of the promised in/out referendum on the country's EU membership.

Conservative MEP Daniel Hannan and Conservative MP Damian Green discussed Mr Cameron's current aims with Jo Coburn.
