ANAS SARWAR has been warned his election pledge of “no austerity under Labour” has come back to bite him amid reports of a £20 billion black hole in public finances.

The Scottish Labour leader is facing criticism after he used a general election leaders’ debate to state: “Read my lips — no austerity under Labour.”

His comment came after SNP leader John Swinney said during the same debate Labour’s plans would lead to £18bn in cuts.
