Boris Johnson's blunt refusal to grant a second referendum on independence could push more voters towards ending the Union, a former Yes campaign chief has predicted.
Dennis Canavan told the Record that the Prime Minister's "intransigent refusal" to grant a section 30 order could backfire.
The former Labour MP, who chaired the Yes campaign advisory board in the run up to the 2014 referendum, backed Nicola Sturgeon's decision to seek Supreme Court approval for her referendum plan.
