Unpaid Work Experience (Prohibition) (No. 2) Bill

I am pleased that the hon. Gentleman recognises the value of short work experience placements, but does he also recognise that sometimes such placements are better structured for both sides, perhaps on a part-time basis or even for one day a week? That means that, although they are probably still rather less than 20 days in total, they can last for significantly longer than four weeks. Is there not a danger of their being caught by his Bill?
