Says the campaign was initiated by SCM Private. If you go to their website, yes they have a lower AMC than some - at 0.75% + VAT (hence 0.9%) - but their Long Term Return Portfolio shows returns since 8 June 2009 of 49.3% (to Jan 2013).
That underperforms the FTSE Allshare which appears to have gained 54.7%
Suggests it would be better to stick to FTSE trackers with higher AMC, e.g. 1.5%, than SCM's Long Term Return Portfolio with lower AMC.
Moral (imo) - it's not fees that matter, it's net return after fees to the investor that counts
