Political commentator Mike Indian discusses what will happen to the SNP after the resignation of Humza Yousaf. With devolution now 25 years old, he highlights the problems faced by all single-issue parties and believes it cannot defy gravity for much longer. He highlights the OECD report that the UK will be the worst-performing G7 economy next year, which should worry Labour as well as the Government. And he looks at Labour's apparent decision to abandon its pledge to ban zero-hours contracts.
