Wooden sona Parked and never moved for over 2 years

Hi, the parking is getting more difficult here and that big wooden sona in photo 1 has never moved for over 2 years and has never been used, there is no numberplate and lights are broken and we are all paying our road tax to park on road when that is not and that silver trailer in photo 2 had been here for days now and had never moved and either. I would love it if something can be done to get them removed because it's getting more difficult to park here and that is an extra 2 spaces being taken by those untaxed trailers. It's on prestongrange terrace on the corner joining onto county road in prestonpans, east lothian thanks.
