Here is the link to Robin’s interview.

Please listen carefully to Robin’s language as some people haven’t. When he says “. . . application to join will be considered . . ” He means just that since it is the National Council and not Robin that would make the decision.
When he says that the English Democrats might speak to Sinn Fein he is correct but it is the National Council who would make that decision not Robin, or anyone else for that matter.
