Shareholders of DP World have approved buying Economic Zones World from its majority shareholder and also backed the port operator’s delisting from the London Stock Exchange, the Dubai-based company said on Thursday. The assent was granted at a meeting on Thursday, with the proposals received near-unanimous support from independent shareholders, DP World said in a London bourse filing. DP World last month said it would pay $2.6 billion to Dubai World for its EZW logistics infrastructure firm and would delist from the London bourse due to thin trading volumes. Dubai World owns 80.45 percent of DP World.
