Specialist insurer graduates from AIM.

Lancashire, the Bermuda-based speciality insurer, has announced plans to list on the London Stock Exchange.

The insurer launched on AIM three years ago, and has a market capitalisation of £525m.

Chief executive Richard Brindle told the Financial Times would open up Lancashire to a broader range of investors, and create more liquidity in the shares. He said: "We will be open to a much bigger universe of investors, and that has to offer us more flexibility."
