CapsLock:-TATA move your HQ here and then you can have truly what you want!
I dont think you understand how the world works. Jaguar and land rover are two companies that happened to be owned by a holding company called Jaguar-Land Rover. 100% of the shares of this holding company happen to be owned by an Indian company called TATA Motors, a majority of whose shares are owned by the Tata family and therefore the company is part of the TATA group.
Jaguar, Land rover and Jaguar-Land Rover are all incoprorated in the UK. That makes all three of them british companies that happen to be owned by an indian company. They pay taxes in britain, they fall under the dursitiction of the british government and british law. They are no more an indian company than matrix churchill was an iraqi company.
Many shareholders in TATA Motors are not indian. That does not make it a French/British/German/American company. Chrysler is not italian. GM is not the Queen (who is a large shareholder by right of canada).
The situation would be different if there were a merger. If JLR was legally a part of TATA rather than simply owned by them then it would be termed a 'multinational' company that was headquatered in India.
EDIT: Sorry, forgot to mention that TATA Motors is also a multinational. Not an Indian company. And its stock is traded on the Mumbai, New york and London Stock exchanges.
