Tees Valley Mayor Ben Houchen today reveals more detail on his bold project to revive the fortunes of Durham Tees Valley Airport.

The Conservative mayor has struck a £40m deal with airport owner Peel and has an established operator lined up to drive ambitious plans to restore popular passenger routes and protect business flights.

Mr Houchen will give a speech at the airport before the business case is made public at 5pm.

Today's publication of hundreds of pages of information, including input from independent specialists, comes ahead of a key vote of five Labour council leaders next Thursday in Middlesbrough.

The leaders of Darlington, Hartlepool, Middlesbrough, Redcar and Cleveland and Stockton councils must back the plan to enable Mr Houchen to buy the airport.

He has warned it is likely to close in 2021 if the purchase doesn't go through.

The Labour leaders have reiterated throughout how they share Mr Houchen's ambition for a viable airport, but have stressed the need for forensic examination of the financial detail.
