Broker Heath Lambert has delayed the pricing of its shares for flotation on the stock exchange.
The shares were due to be priced this morning for an issue thought to be worth up to £470m.
A Heath Lambert spokesman confirmed today that the delay had arisen due to the fragility of stock market conditions.
He said the company is continuing to talk to investors and a new announcement will be made in the next few days on how it will proceed.
Heath Lambert said that delaying the float did not mean it would be abandoned entirely.
