Property portfolio : Sol Campbell and his wife Fiona . The polls might have the parties neck-and-neck – but it looks like Sol Campbell is taking no chances . For the second time this year , the former England footballer is selling a multi-million pound property – leading to speculation he wants to dodge Labour ’ s mansion tax if the party wins the election . An outspoken critic of the policy , Campbell has even threatened to leave the country if the tax on properties over £2million comes into force . Earlier this year it was revealed he had taken the apparently bizarre decision to sell a £20million London townhouse to a company owned by himself . Land Registry documents suggest the sale was registered the day after higher stamp duty levies came into effect . But it is possible the sale took place shortly before , meaning the increased charges would have been avoided . Now Campbell has listed a second property for sale in the same exclusive neighbourhood of Chelsea . A former home of James Bond author Ian Fleming , the luxury penthouse by the Thames is on the market for £6.75million . Campbell bought it in 2011 for £4.25million after he reportedly staged a sit-in at an estate agents ’ in the hope of securing it for his family – his wife Fiona Barratt-Campbell and their children Isabella and Ethan . It has since been extensively renovated by his wife , an interior designer and granddaughter of Barratt Homes founder Sir Lawrie Barratt . An advert for the property states : ‘ There are few properties within Chelsea that can offer the combination of views , spacious accommodation and exquisite finish. ’ Yet Campbell , 40 , seems to be keen to rid himself of the flat before the election . Eye for detail : The living room inside Campbell 's £6.75million Chelsea flat boasts lavish furnishings . Nice touch : The former Arsenal and Tottenham Hotspur defender 's kitchen is filled with marble . Sumptuous : Gilded mirrors line the hall in Campbell 's luxurious flat , which is in an exclusive neighbourhood . Last year the former Arsenal and Tottenham defender blasted the proposed mansion tax , describing it as a ‘ cheap and easy way to extract money from individuals who have done well ’ . He told The Times : ‘ With a mansion tax , you ’ re taxing me for being prudent ... If Labour gets in , I ’ d leave . I ’ d have to say , “ Sorry , I want to ship out ” . ’ Campbell has also said : ‘ I ’ m not earning what I was earning five years ago. ’ Experts have said that properties worth between £5million and £10million could incur an annual charge of up to £25,000 under a Labour government . Henry Pryor , a buying agent and property commentator , said : ‘ Sellers like Sol Campbell face a financial dilemma : to take a certain hit now or await the potential tax bill that a Labour or Lib Dem Government may generate. ’ Since 2009 Campbell has also owned Grade II-listed Hallington Hall , an 18th Century mansion in Northumberland .
