Nicolas Sarkozy ’ s most senior aide regularly mocked him as a ‘ dwarfish Napoleon ’ , an ‘ airhead ’ and a ‘ nutter ’ , it was claimed last night . The revelations will come as a huge blow to the former French president , 60 , who is aiming for re-election in two years . Adviser Patrick Buisson , 65 , was credited with steering Mr Sarkozy into the Elysee Palace , where he served between 2007 and 2012 . Nicolas Sarkozy 's ( left ) most senior aide Patrick Buisson ( right ) regularly mocked him , it has been claimed . But a book called The Bad Genie claims Mr Buisson frequently mocked the 5ft 5in politician , who wore stacked heels , especially when with his third wife , former supermodel Carla Bruni . Mr Buisson , who is an expert on opinion polls , said Mr Sarkozy could 'do nothing without me ' and would call him all the time . 'It was the Dwarf ' or 'the Little One ' , Mr Buisson would tell colleagues after receiving a call from Mr Sarkozy . Mr Buisson was viewed as a 'compass ' and 'genius ' by Mr Sarkozy , despite also being referred to as a 'nutter ' or 'airhead ' . Sarkozy wore stacked heels , especially in the presence of his third wife , supermodel Carla Bruni . Mr Buisson would not think twice about slamming the phone down on Mr Sarkozy , saying : ' I 'm having lunch , you 're bothering me ' . He would also put Mr Sarkozy 's voice on speaker , and laugh about him with friends , saying : 'He can do nothing without me , Naboleon ' . The nickname was a cross between 'Napoleon ' - the legendary French leader - and the term 'nabot ' , which means dwarfish . Authors Ariane Chemin and Vanessa Schneider , who both write for Le Monde , said Sarkozy would phone Mr Buisson for 'reassurance ' more than his wives . Mr Buisson fell out with Mr Sarkozy last year , after it emerged that he had recorded many of their conversations without the politician 's consent . In one , Carla Bruni dubs her husband a 'kept man ' , thanks to her fortune amassed during her time as a model in the 1990s . Mr Sarkozy went on to sue his former mentor for around 70,000 pounds , saying : 'In my life I 've known betrayal , but rarely one like this . ' Mr Sarkozy was defeated by Francois Hollande , his detested Socialist rival , in 2012 after just one term in office . The conservative leader of the UMP Party is determined to get back into power , but is facing a range of corruption enquiries . They include claims that he received millions in back handers from former Libyan dictator Colonel Gaddafi . Mr Sarkozy denies any wrongdoing .
