At a national level, the only person I can think  of who’s been on our screens regularly since the 1980’s and still on is Kay Burley.

Kirsty Wark is the only other presenter I can think off. If you expand out to correspondents, or presenters turned correspondents then the likes of Nicholas Witchell and John Simpson come to mind

Lorraine Kelly? Perhaps she strays too far towards entertainment to count.
