The international arm of Russian bank Otkritie Capital posted profits of nearly £50 million in 2013, as heavy trading in Russian securities helped the broker surge back from losses totaling more than £60 million in the prior two years.

London-based Otkritie Securities Ltd reported post-tax profits of £49 million for last year, compared with a loss of £9 million in 2012, according to accounts seen by Financial News.
