Plans to ban smoking in school and hospital grounds and playgrounds in Wales have been launched.

But this second attempt to bring in the Public Health Bill does not include a controversial ban on e-cigarettes in some enclosed places.

The Welsh Government plans, first outlined in 2014, still include tattooing and piercing regulation.

Public bodies will also have to assess the effects on physical and mental health of any decisions they make.

If there was a plan to build a new road or open a fast-food restaurant near a school then councils, for example, would need to consider the health impact.

The first attempt at passing the legislation was defeated in March and First Minister Carwyn Jones said there was "no point trying to bang our heads against a brick wall when it comes to e-cigs".

Public Health Minister Rebecca Evans, who launched the proposals at a children's playground in Cardiff, said many of the measures included in the original bill had cross-party support and there had been "widespread disappointment" when it failed.

"At the heart of the bill is the aim of promoting the health of children and young people," she said.

"Proposals such as the ban on smoking in school grounds and playgrounds is intended to prevent children from being exposed to smoking behaviours, making it less likely that they'll take up smoking themselves."

She said, overall, the health of people in Wales was improving but there were challenges and she wanted to see the pace of improvement increased.

There is hope the bill will be passed by May next year.

The Welsh Government sees this as an important piece of legislation to improve public health, especially for children.

The Bill should get a smoother ride because the elements which divided opinion, like e-cigarettes are not there. Originally, this Bill also included a minimum price for alcohol, but this was set aside because it was thought it would be challenged in the courts. So that is being pursued in a different way.

I think it is fair to say Dai Lloyd, the chairman of the assembly health committee and some of the professional bodies like the Royal College of Nursing might be a little frustrated that this might be a missed opportunity to be more novel and forward looking.

But the aim of the Welsh Government is to get those elements which have been agreed onto the statute book and it expects that to happen by next Summer. But this is the assembly and the whole process of scrutiny starts again.
