Currently MP's are allowed to claim from the tax payer for a second property in London, these expenses vary from MP to MP but costs the UK taxpayer hundreds of thousands of pounds a year, every year. 
As a country we should own 650 properties, these should be tax payers assets. MP's will be allowed to use the property for a peppercorn rent from their £79,468 salary until they either give up their seat or lose it, then whoever takes their seat gets to use the property on the same basis. We should not be consistently giving MP's money for properties that they then keep, the use of one of the countries properties should be the only option. 
Everyone else in the country is taxed for "perks" of the job, but MP's systematically abuse the UK tax payer to their own gains.... It's time to make a stand.
