Since 2010 , Mrs Cameron has worked as a creative consultant for the company two days a week . Samantha Cameron received an estimated £400,000 windfall from the sale of the luxury stationery company where she works , it was claimed last night . Smythson was bought in April 2005 by a group of prominent City figures for some £15.8million . According to a report by The Guardian last night , Mrs Cameron would have received £1,589.20 for each of her 275 shares , giving her a lump sum windfall of £437,000 before tax as a result of the sale . The company was acquired by a consortium of City grandees , including some who have donated to the Conservative Party . At the time of the sale on April 30 , 2005 , Mr Cameron was the Tories ' head of policy coordination , a largely back office role . He was appointed shadow education secretary six days later , in the wake of the Tories ' election defeat . Among those who were reportedly involved in the deal were Jonathan Green , the founder of the GLG hedge fund , Howard Shore , who set up the stockbroker group Shore Capital , and members of the Fleming banking family . All are Tory donors . Last night a spokesman for Samantha Cameron said : 'The sale of Smythson happened before the 2005 General Election , when Michael Howard was leader of the Conservative Party . 'Samantha Cameron was not a board director and was not responsible for the sale . It would be entirely wrong to suggest any wrongdoing or attempts to obtain undue influence . ' Mrs Cameron began working at Smythson as a window dresser in 1996 , the same year the couple married . By the time of the sale she was creative director . The Guardian also reported that Mrs Cameron will have received a second windfall when the firm was sold again in 2009 because she held shares in the new parent company , although this was estimated to be a 'much smaller sum ' . It is calculated that Samantha Cameron received more than £400,000 before tax from the sale in April 2005 . Since 2010 , Mrs Cameron has worked as a creative consultant for the company for two days a week . Smythson 's store in central London 's New Bond Street sells among its stock £2,000 python-skin handbags . Mrs Cameron is thought to earn up to £100,000 a year . Mr Green reportedly gave the Tories more than £40,000 and also financed Mr Cameron 's leadership campaign . Mr Shore has given the party £34,000 personally while Shore Capital has donated more than £580,000 to the Tories , it was claimed . Last month the Mail revealed the firm is owned through a holding company based in Luxembourg , a tax haven . It is also linked to a secretive trust in the Channel Island of Guernsey , another well-known tax haven . Mr Cameron has publicly criticised tax avoidance in the past , including a warning to businesses setting up 'ever-more complex tax arrangements abroad ' which he said should 'wake up and smell the coffee ' – a jibe aimed at Starbucks , which has paid only small sums of tax in the UK . David Cameron himself is estimated to be worth around £3million . His house in North Kensington – which is currently being rented out – is thought to be worth around £2.7million , and he also owns a home in Oxfordshire which is worth close to £1million . And as well as their personal wealth , the Prime Minister and his wife come from very well-off backgrounds . Mr Cameron 's father , Ian Cameron , was once estimated to be worth around £10million . He died in 2010 and left a fortune of £2.74million , from which Mr Cameron received £300,000 . Mrs Cameron 's father , Sir Reginald Sheffield , is the eighth holder of a baronetcy that goes back to 1755 and is estimated to be worth at least £20million .
