David Nicol, chief executive said: "It has been another quarter of steady progress towards our long-term growth goals. Our core discretionary business has continued to deliver organic funds flow and income growth, demonstrating its resilience in the face of uncertain market conditions. In times of market volatility our clients are increasingly looking to Brewin Dolphin to guide them through challenging investment markets.
“We remain committed to our growth initiatives and have made good progress during the quarter,” Nicol added. “Our confidence in the future is underpinned by our robust financial position and clear strategic focus."
