Came through the dartford tunnel for the first time tonight, in the
right hand land, and noticed, just underneath the 50 limit, a white 10
on a blue background - is this a minimum speed limit sign? I didnt
think the UK had them.

Yep. In the Highway Code and I've seen them elsewhere too.

Why is it only on a 300 yard stretch?

No idea.
