With just 24 hours until nominations open in the Scottish Conservative leadership contest, Murdo Fraser has stuck his hand up. That makes six contenders so far to replace outgoing leader Douglas Ross. Fraser has stood for the post before, in 2011, but lost out to Ruth Davidson. Perhaps the pivotal reason for Fraser’s defeat was his radical proposal to scrap the Scottish Tories and set up a new centre-right party separate from the UK Tories but sitting alongside them in government and opposition.
