Watching their weight but not their tax bill

A recent UK tax ruling is likely to have a significant impact on profits at the US slimming company Weight Watchers. 

Weight watchers could be served a charge of $37m (£23m) after a tax tribunal rejected claims that its leaders, who run diet meetings, are self-employed. 

The tribunal upheld a decision by HMRC in 2007 that the leaders were employees and so subjected to salary deductions, including National Insurance payments. 

The size of the bill relates to unpaid taxes covering the period from April 2001 to year end 2009, with estimated accred interest on top.
