Shares in betting firms leapt after Wednesday’s budget contained no rumoured tax changes.

Earlier this month, the Guardian suggested that the Treasury was considering proposals to increase gaming duty from two think-tanks which could have raised as much as GBP3 billion.

However, Reeves was silent on the subject, sending share prices higher.
