The most convoluted saga in car industry history is due to end this August when VW will buy the 50.1% of Porsche's parent company that it does not already own.
This ends a battle that started in 2005, when Porsche, bizarrely, started buying into VW and then tried to swallow its vastly bigger German neighbour. Think of those wildlife films where a snake swallows a deer, but substitute an elephant for the deer, and you get the idea of the difference in scale.
Porsche first bought 18.5% of VW in late 2005, apparently at VW's own request, to prevent hedge funds buying into the German giant. Then Porsche decided it could buy VW itself and increased its share to 30.6% in 2007 and had control of 75% of the shares by October 2008. However, VW refused to give control to Porsche, hiding behind a rule that said no shareholder had more than 20% voting rights, regardless of shareholding. This was ruled illegal under EU Competition Law, but Chancellor Merkel simply said Germany would ignore the ruling. Yes, that is the same Chancellor Merkel who now insists that all EU countries abide by European fiscal regulations.
