He was scheduled for a crown court trial when he died. The case was then obviously dropped.
The story of the Edwards family is an interesting one. Martin is now a very wealthy individual following the sale to the Glazers but it wasn't always so. The story of how Louis wormed his way into United involves some luck and a lot of dodgy dealing.
His association started in the early 1950's when his business was doing well and he had plenty of money in his pocket. He became close to Busby and many of the other key figures around the club but wasn't a director. But in the week leading up to the Munich disaster, he had two strokes of luck. The first was when a board member called Whittaker died in his sleep the night before their last league match before going to Belgrade. The obvious candidate to replace him on the board was a man called Willie Satinoff. My uncle was a director at the Satinoff family firm, Alligator Rainwear, so we knew the family well. Unfortunately Willie was on the plane at Munich and died in the crash so the board invited Edwards to join them.
He started with just a few shares but when he floated the meat business on the stock market in the early 1960's he began a process of quietly buying up more shares with his newly acquired wealth. The other directors eventually got a bit concerned that too much control could be gathered in a single pair of hands and put together an agreement that the three main directors - Edwards, Harold Hardman & Alan Gibson - wouldn't buy any more shares. Despite agreeing to this, Edwards carried on, getting associates to secretly buy up small shareholdings for him until he had acquired over 50%. This involved falsifying share register entries of course as although it was his money that had bought these shares, he couldn't be seen as the owner.
The 1960's were a great time for United but in the following decade their fortunes declined, as did Edwards', with his business doing poorly. At the time, there were FA rules about dividends which limited the amount per share that could be paid. I think it was 2 old pence per share. That was no problem to Edwards as he arranged a rights issue of 208 shares for each one currently held. This had two benefits to him; the first was that he could now pay himself two hundred times as much via dividends and it also allowed him to buy up more shares on top of the ones he was entitled to, giving him the vast majority of the shares. Martin also got "invited" to join the board, despite him not even being a big football fan. He had to borrow hundreds of thousands of pounds to take up the rights issue but he could then be a paid director.
By the end of the 1970's the business was in trouble and the World In Action programme that revealed his alleged venality caused it to collapse completely, followed by Edwards' death in 1980. Martin then became the effective owner and was allegedly cash poor, with a significant overdraft. Over the next few years he tried to sell the club, first to Robert Maxwell then to Michael Knighton. Eventually they floated on the stock market, which certainly enriched Edwards but probably did little for United's finances. There was a final attempt to sell the club in 1998, involving Sky, but that wasn't carried through, possibly due to the threat of an investigation about conflict of interests. Finally dear old Uncle Malc and his boys came along in 2005 and Edwards made a further pile.
