Thanks. This is very interesting. At the time, I will in contact with someone who was a professional adviser doing work for the club. He told me that, at the beginning, Thaksin was funneling money into City from offshore accounts whose existence was disclosed by way of Thaksin offering proof of funds when buying the club. However, the intention was always for Thaksin to invest in the club using money he had in Thailand. IIRC, he had a couple of billion quid frozen there, but he expected the party loyal to him to win the Thai general election in December 2007.
He thought that victory would then trigger two developments: (1) the unfreezing of his billions in Thailand, which he could then withdraw from the country through MCFC outside the scope the restrictions of general Thai currency control legislation using an exemption concerning investments that enhance the prestige of Thailand internationally; and (2) the disbanding of a body called the AEC (Assets Examination Committee) which had been set up by the previous military government to look into Thaksin's offshore funds. But, though the largest single party in the Thai parliament, his allies fell short of an overall majority and neither of these things happened - which had serious repercussions for MCFC.
As discussed in another thread, MCFC had set up a deal to bring Nicolas Anelka back to the club in the January 2008 transfer window and that transaction fell through, obviously. He ended up going to Chelsea, where he in effect understudied Drogba, but he'd have opted to be the main striker at City under Sven had that option remained on the table. At this stage, Thaksin no longer was prepared to channel funds into the club from his offshore accounts lest he alert the AEC, watching on closely, to the provenance of the cash.
Thaksin's preferred solution was to bring money into MCFC by finding a partner who'd subscribe for a minority shareholding at a hefty price, and it was this plan that first brought ADUG into the picture. Thaksin's adviser Pairoj Piampongsan, a director at City, was based in the UAE and had top-level contacts over there. I believe that, even at this stage, ADUG regarded MCFC fairly favourably as a potential investment but their plans didn't involve playing second fiddle to anyone (and Thaksin's valuation of the club coupled with the amount of control he was prepared to cede didn't enhance the prospect of doing a deal with anyone).
As 2008 moved forward, it became clear that Thaksin's political woes in Thailand, his resultant inability to finance MCFC and the British government's decision to side with his enemies meant that he was always likely to have to sell the club on. Unfortunately, he was very slow in recognising the fact, believing for months that a solution would present itself and allow him to retain control of the club. That nearly cost us the ADUG takeover. I suppose we should thank the Thai military for ending up putting Thaksin in a position where, just in time, even he couldn't deny that he needed to get out. ;)
