Totally different to MPs fiddling expenses! Claiming for a mortgage that was already paid off etc no comparison at all

To avoid going into the higher tax bracket this year I had 2 options, C2W scheme, or increase pension contributions. If I increase my pension contributions to avoid paying higher rate of tax is that morally wrong too??
I have a clear conscience using the scheme. My new bike used 7 times, approx 240 miles, 2 leisure rides 80 miles & 5 commutes at 160 miles, well within the scheme requirements.
