NEW DELHI: Companies House , a UK government department, has confirmed that the 2005 and 2006 returns of Backops, a private company set up in the UK by Rahul Gandhi in 2003, show the Congress vice-president’s nationality as ‘British’ but said it “could very well be an error made by whoever submitted the information”.A press office representative of Companies House on Tuesday attested to the genuineness of the Backops’ 2005 and 2006 returns that showed Gandhi’s nationality as ‘British,’ but said these were electronically filed and authorised by a director. However, Companies House, the British equivalent of India’s Registrar of Companies, said it was unable to establish whether it was “Mr Gandhi himself or an authorised person such as his accountant/solicitor filing on his behalf” who filed the returns.“Mr Gandhi himself would need to clarify this,” said the representative. Backops was represented by tax advisory and accounting firm Tax Innovations Ltd based in Winchester, Hampshire, as per the documents filed with Companies House.Under UK law, a person filing false information would be guilty of an offence and is liable on conviction for imprisonment up to two years or a fine (or both). But it has to be proved that the person submitting the information knowingly or recklessly filed false information, as opposed to it being a simple administrative error.On Monday, senior BJP leader Subramanian Swamy alleged that Gandhi had declared himself a British citizen in the registration papers of Backops, which was dissolved in 2009. The Congress denied the allegation about Gandhi’s nationality saying that from the day he was born, he had never held citizenship of any country other than India, “nor has he represented as such”.The office of Rahul Gandhi did not respond to a detailed questionnaire emailed by ET seeking comments.Congress spokesman Randeep Surjewala, who was also sent the same questions, said he did not have anything to add to Monday’s statement.Simon Griffiths, managing director of Tax Innovations, declined to comment citing client confidentiality. The address that Gandhi provided in the annual returns of Backops, whose principal activity was providing consultancy services, is located in North London’s tony Hampstead area and according to Mouseprice.com, a UK property database, potentially commands a valuation of 13 million pounds (`130 crore) now.The property 2 Frognal Way was sold in March 2006 to Nadia-France Isaacs and Martin Charles Isaacs for 4.1 million pounds, according to data obtained from the UK land registry. The identity of the seller is not known. The same property is also listed as the address of Ajitabh Bachchan, brother of actor Amitabh Bachchan, and an old friend of the Gandhi family, by CheckCompany, a UK website that specialises in providing information about companies and their directors and officials.
