JP Morgan Cazenove&rsquo;s (JP M Caz) top dealmaker Ian Hannam was the chief adviser on the Heritage-Genel merger.<br /><br />He&rsquo;s tipped to be the big beast of 2009&rsquo;s bonus pool, having reeled in most of the company&rsquo;s big deals.&nbsp;&nbsp; <br /><br />He, along-side JP M Caz&rsquo;s new chief executive, Naguib Kheraj, secured advisership on the HSBC, Xstrata, Land Securities and SVG Capital cash calls.<br /><br />Hannam has worked on more major deals in London than any of his contemporaries, but he missed out on the JP M Caz chief executive job last year.<br /><br />The decision to appoint Kheraj ruffled feathers at JP MCaz, and it was much-speculated that Hannam would quit, having lost out on the job.<br /><br />Hannam also lost out on a record breaking deal with US company Dow Chemical in 2007. <br /><br />The $18.8bn (&pound;11.56bn) purchase of Rohm &amp; Haas was advised by Citigroup, Merrill Lynch and Morgan Stanley, after a cloak-and-dagger takeover deal involving JP M Caz turned nasty. In a John Le Carre-style episode, a nasty legal spat blew up between Dow chief executive Andrew Liveris and two ex-senior officials at the company who secretly explored taking it over. JP M Caz came clean about its involvement in the secret talks, losing Hannam the deal.<br /><br />Hannam is ex- Bermondsey grammar, a Millwall fan and an ex-member of the Territorial SAS.<br /><br />
