The multi-millionaire who  owns La Fortaleza in Puerto Pollensa is James Lupton, CBE, one of the Conservative  Party’s chief fund raisers.Lupton, is co-treasurer of the Conservative Party and the chairman of investment bankers, Greenhill Europe, which he  helped found  and has a global network of corporate relationships in the healthcare sector.
Prior to that, he was at Barings Bank from 1980 until the bank was collapsed by ‘rogue trader’ Nick Leeson in 1995.
 Lupton was a director at the bank in 1995, the year that it went bust.
 He became deputy chairman when the top bosses quit and stayed on for three years under its new Dutch owners ING. As the Bulletin reported yesterday, on Monday night, the Conservative Party held their annual ‘Black and White ball’ election fundraiser at the Grosvenor  Hotel  in London and the star item in the auction was a week for 24  people at the La Fortaleza exclusive estate, which Lupton is understood to have purchased for 40 million euros,  in Puerto Pollensa.
The estate has a 17th century fortress with five bedrooms, five more houses, two swimming pools, and a helipad.
