Left Foot Forward, who are not impartial, are alleging that the Daily Mail are spouting rubbish. That in itself is a pretty fair suggestion. The specifics cover this article on quangos "The cost of quango Britain hits £170bn - a seven-fold rise since Labour came to power".
The Left Foot Forward article here alleges that the Mail use Taxpayer Alliance figures which are "not a like-for-like comparison". With statistics, precision is everything and the odd thing here or there makes all the difference. In this case, not comparing like-for-like allows the latter figure to be overblown in order to give the effect they are after.
Bloody Daily Mail
Bloody Taxpayers' Alliance, a real nasty lot
