It's not the end, there's more to come. That was the message from ministers with the launch of the soft drinks sugar tax.

There was a clear hint that further anti-obesity policies are not far off. The government seems emboldened to press on with strategies aimed at persuading companies to cut calorie content and to wean consumers off their fast-food habit.

First of all, policymakers may well consider extending the scope of the sugar tax to flavoured milk drinks. They were left out of the scope of the levy when it was first announced in 2016.

But the instigator of the policy, George Osborne, when he was chancellor, now says he wishes he had gone further at the outset and included sugary milk drinks in the tax net. He hinted that current cabinet members should move more rapidly.

Speaking to the BBC's Newsnight, Mr Osborne said: "I was already, before I left office, looking at whether you could extend it to sugar added to milk products like sugary milkshakes. I think it'll be for others to take further steps forward and I would predict those steps will be taken."
