Middlesborough and Hull are not in Yorkshire

Yes they are

Yes, they both have that misfortune nowadays.

Middlesbrough really isn't

Hey, BD, nowt wrong wi Yorkshire!

tres good

Middlesbrough is a town & a pretty grim one at that.

Complicated past has Middlebrough but according to the BBC, Wiki and Brittanica it sits in the ceremonial county of North Yorkshire, where it is the largest town. The council situation would have it as being Middlesbrough in Middlesbrough (which is novel); Teeside having bitten the dust in the 1970s and Cleveland in the 90s.

Spelling Middlesbrough incorrectly should be a hanging offence. FWIW Middlesbrough FC play in the North Riding Senior Cup - I think that settles definitively any debate about whether it's in Yorkshire.
