Opened just four years ago as part of a multi-million pound modernisation programme, Luton Airport's terminal car park two has suffered a structural collapse after a huge fire ripped through it. So, what happens next at Luton, the UK's fifth largest airport?

The fire started on level three of the airport's terminal two car park.

Fifteen fire engines and more than 100 firefighters from Bedfordshire, Buckinghamshire, Cambridgeshire, Hertfordshire, Northamptonshire and London were sent to the car park.

The fire service said the car park was not fitted with sprinklers.

It is thought the fire started with a diesel-powered vehicle "and then that fire has quickly and rapidly spread", said Andrew Hopkinson, Bedfordshire's chief fire officer.

The fire service said a full investigation into the blaze was under way. It is not known how long it will take.
