Strange vine-like plant just popped up... Help needed identifying please
 

Hello,

I'm new here and joined mainly to ask for some help identifying a plant as we are concerned it could be destructive but are not experienced enough to be able to identify.

The plant in question has suddenly popped up alongside our front wall, and appears to be creeping under the new turf as well - can you tell what it is and is it something we need to worry about?

Thanks and nice to meet you all!
Dan
