Forbes has entered the race, and I think that may be it. A field of Forbes, Regan, and Yousaf. Apart from GRRB differences, the only diffetentiator so far has been Regan talking about a more direct claim to what a mandate for indeoendence is (see attachment), and internal party democracy changes.
Be interested if we start to see something from Regan on freeports, as in opposition, and local democracy.
The Salmond case haunts the make up of the field.
