There is no significant conflict between the Howard Reed data and the Treasury data [distributional annexe] for the 50 %
of public services spending data which the Treasury include.
But none of these issues could alter the issue of the progressive distribution
of public service spending, see this July 2010 report.
When
the public service spending, tax, tax credit and benefit changes are taken into account (ie, everything), the effect on households in 2015/16 is bad news - an average drop of 2.5 %.
And that is what Clegg is getting at - the issues you refer to can and do alter the issue of the progressive distribution of
public service spending.
