The Dumbarton Scottish Parliament constituency could be set for a radical shake-up, that would see some villages near Helensburgh moved to a different seat.
Currently the Dumbarton constituency, which has been served since its inception by Labour’s Jackie Baillie, covers Dumbarton, Alexandria and Helensburgh.
It also includes the smaller villages of Rhu, Garelochhead and Arrochar - and the Rosneath peninsula.
