Highbury House has sold its business division, including the Nexus titles, for £12.5m to US company Ergo Science. The sale covers 45 magazines, including Motor Trader, World Fishing Magazine, Export Times, World Travel Guide and Electronics World . The deal should be completed in April. Highbury has been trying to offload the division for more than a year to concentrate on its consumer magazines, such as Front and Fast Car. The company, which publishes 200 titles and bought up Cabal last year, has said it received an approach from a potential bidder last month.
