RUTH DAVIDSON has warned her fellow Tories not to “dismiss” Jeremy Corbyn on the grounds that he is “just an old Marxist.”

The Scottish Conservative leader spoke out against such “identity politics” after numerous party colleagues, including Prime Minister Boris Johnson, used the description in an attempt to discredit the Labour leader.

Last month, Mr Johnson described Mr Corbyn as “the leader of a cabal of superannuated Marxists.”
