ANAS SARWAR faces fresh calls to “get his house in order” today, after his adviser was accused of running “a constant undermining campaign” against Jeremy Corbyn and Richard Leonard.

Mr Duncan was in the spotlight yesterday after the Red Robin website drew attention to a series of his outbursts on social media.
