Clyde & Co’s merger with Barlow Lyde & Gilbert has propelled the firm to the largest hike in revenue among the UK top 50 this year, with turnover jumping 35.4%.

After joining forces with Barlows in November 2011, the firm saw fee income hit £287m for 2011-12, up from £212m last year. Turnover on a like-for-like basis at Clydes without any contribution from Barlows grew 17% to £248m.
