As the name suggests, this seat takes in the eastern chunk of County Londonderry, and the area has been represented in the commons since 1974 by Willie Ross.
His seat today is largely rural, including parts of the Sperrin Mountains, the Roe Valley, most of the eastern shore of Lough Foyle and part of the northern coast of the province.
Much of the Coleraine half of the seat is extremely picturesque and very attractive to tourists.
Coleraine is a busy shopping town with a little industry, also site of the University of Ulster, whilst Kilrea and Garvagh are small market towns.
The roads linking Coleraine, Portrush and Portstewart are the site of the annual North-West 200 Motorcycle Races.
The area covered by Limavady District Council makes up the western, more rural, half of the seat. The town is a former home of William Massey, Prime Minister of New Zealand from 1912 to 1925. His statue can be found in the town; it was also home to Jane Ross, who noted down the famous Londonderry Air or Danny Boy from a street fiddler in 1851. Dungiven is a pleasant market town situated where the rivers Roe, Owenreagh and Owenbeg converge at the foot of the 1,535ft Glenshane Pass.
