Here are some potential seats for Northumberland and Tyne and Wear. I based it on the 60,000 figure meaning Northumberland has four and Tyne and Wear thirteen seats. Unfortunately crossing the Tyne was unavoidable with Tyne Valley seat in the western Newcastle suburbs crossing the river. Seats that look unnatural for borders are usually based on transport and communications links (7, 8 and 14 all follow the Metro line for instance, 8 follows the Coast Road that it is named after, 10 follows Scotswood Road and 3 follows a major A road too). I of course have a personal interest in the region, being from the Gateshead West constituency, and I have used this local knowledge to try and preserve community ties where possible.
