Integro has attempted to scotch speculation that it is under pressure from investors to improve its performance.

There had been rumours that investors, including investment management firms Highfields Capital, Century Capital, Credit Suisse First Boston and Byrne & Fils, have given the company until July to produce results.

One market source said: "[Integro] has resourced itself heavily and continues to do so, but the revenue isn't following as it would hope – this is a common situation with all new businesses."

But, Roger Egan, chief executive of Integro, dismissed the suggestions as "disinformation".

"We have had a very good year and we are growing according to plan with almost two-thirds of our original capital remaining," he said. "Our investors know that this is a three to five-year build and they're all in for the long term."

Speculation about Integro's future comes as it announced plans to set up an international insurance and reinsurance operation in the UK, building on the acquisition of specialist PI Lloyd's broker, Humphreys Haggas Sutton, in 2005.

Egan said: "It is a major initiative on our part and we will probably hire at least 50 people this year, which will grow to 100 next year.

"We will quickly broaden the business to encompass P&C lines, management risks such as D&O, crime and fidelity. "
