DP World owns 49 ports around the globe
DP World, the container port business owned by troubled investment group Dubai World, is to seek a share listing on the London Stock Exchange.
The planned listing would be the second for DP World, which has been a member of the Dubai Stock Exchange since 2007.
DP World, which owns 49 ports around the world, said it aimed to float in London in the second quarter of 2010.
State-owned Dubai World made headlines in November when it sought to delay repayments on its $26bn (£16bn) debt.
The Dubai government was subsequently bailed out by United Arab Emirates neighbour Abu Dhabi.
Dubai announced on 14 December that it had been given $10bn from Abu Dhabi, with $4.1bn going directly to Dubai World to cover its latest debt repayment.
