A multi-million pound investment plan for southern Scotland and northern England is set to be officially agreed.
The Scottish and UK governments have confirmed £350m towards the Borderlands growth deal.
Dumfries and Galloway, Scottish Borders, Northumberland, Cumbria and Carlisle City councils and other local partners will add in more than £100m.
They are carrying out an online signing of the deal which it is hoped can deliver more than 5,000 jobs.
But where will the investment be made?
