Does the UK need a National Security Adviser, Taliban piece talks and a shortage in aircrew training

This week we are joined by Dr Julian Lewis, Chair of the Commons Defence Committee to discuss defence spending and why the UK needs a full time National Security Advisor. Christina Lamb, chief foreign correspondent for the Sunday Times talks about the Taliban peace talks and whether they will bring long term piece to Afghanistan. Paul Beaver is an aviation expert and we talk to him about the National Audit Office report suggesting military aircrew training is coming up short. And we remember the start of the Second World War.
