We still need a Zacchaeus moment

This has to be one of the saddest weeks of my 9 years involvement in British politics.
Distressed for the honourable MPs who have always kept their expenses within the spirit of the regulations and are now smeared either by false allegations or by association with their greedy colleagues.
Despairing at the damage done by the Chancellor of ALL people who flips his homes 4 times to avoid paying tax!!! Is he so cocooned that he doesn't understand that this is carte blanche for all those considering other forms of tax evasion?
Outraged for the sense of betrayal felt by the Conservative Party at large, that is made up of wonderful, ordinary people who for no personal gain give time, money and energy to further the freedom and democracy that they care so passionately about. 
Miserable that our precious democracy is jeopardised by the deepening apathy and disengagement that this scandal has engendered amongst the electorate.
I previously called for radical, immediate action - a Zacchaeus moment - in British politics. There is no more time to lose. As well as previous suggestions I would add another. The MP's main home in the constituency or in London should be bought, owned and maintained by an arms-length organisation that is wholly owned by the State so the asset remains with the taxpayer. Just as vicarages up and down the country are established in the parish for successive incumbents and owned by the Church of England [roughly - I'll spare you the details], a house from which the MP serves his or her community should be made available. This wouldn't stop those with the means to buy their own place or live out of two homes, but it would put an end to the practice and perception of profiteering from home allowances.
Some will say that this will deter good people from entering politics. I would say that the first time I heard David Cameron speak he talked of service and sacrifice. Now, with depression on one side and scandal on another, more than ever we need to rebuild the reputation of the British politician - and this has to be demonstrably based on the virtues of frugality, integrity and good stewardship.
