Both individuals in the attached clips speak the same native language. Can you guess what language that is (it's not English)?

Both are speaking with British accents but the first is given away by the way that his accent wavers between RP and Estuary. The second I would have put down as a Londoner.

The first has hints in his pronunciation which I would have guessed as German but there isn't enough there to judge without a hint.
