Herbert Smith has racked up $100m (£51m) in fees for work representing the Republic of Tajikistan in an ongoing legal battle with a group of aluminium traders.

Costs disclosed in the High Court last month (April) in front of Mr Justice Tomlinson reveal the firm is set to bill approximately $100m on the case, which sees it advising Tajik Aluminium Company (Talco) as it seeks damages of more than $485m (£244m).
