Health Secretary Andy Burnham, who supports the Bill, is likely to announce to MPs that ministers have accepted the scientific arguments for preventing children from using "leccie (electric) beaches". These are the artificial sunbeds.
Cancer Research UK suggests that anybody below 35 using a sunbed may develop skin cancer. It warned that more than 250,000 children were risking their health in search of a tan, and were driven mainly by peer pressure.
Malignant melanoma, the deadliest form of skin cancer, causes more than 2,000 deaths a year in Britain, of which one in ten cases is under 35.
The Bill has been introduced by Julie Morgan, Labour MP for Cardiff North. It will have its second reading on 29 January. To get passed, at least 100 MPs should support it.
Charity Cancer Research is worried if the Bill will get sufficient support from the MPs.
