UK to ban unpaid internships?

It's been long rumoured in the industry that Britain had unpaid internships under review.  Well years later, it looks like they're actually on the brink of doing something about it:

A mole has told us that HMRC are soon to publish a set of guidelines which recognise “internships” in terms of the National Minimum Wage.

If true, these guidelines will say that internships are a “step up” from work experience; suggest a longer time period; and crucially they MUST BE PAID.

We understand this document will be relevant to all areas of work, and will give all employers an official document to be referred to follow.

The announcement is rumoured to be due next week.
