Fun and games that the Government's response to a petition about the pollution of the Rivers Severn and Wye seems to cede a great deal of English territory to Wales.
But Edmund Mortimer and Henry Percy, 1st Earl of Northumberland agreed to Owain Glyndŵr's territorial demands under the Tripartite Indenture of 1405.
That agreement strongly suggested that much of England had a predominantly Brythonic population at the time. And that in turn rather suggests that, if by a great deal less, it still does. But why did Glyndŵr not demand Cornwall?
