More than a quarter of investors are now less confident about the stock market than they were before the war on Iraq started, research has showed.

About 27 per cent of people feel less confident about investing in shares.

Almost half said they were still concerned about the state of the economy, while six per cent thought going to war had increased the threat of global terrorism, according to the Association of Investment Trust Companies.

But 15 per cent of those questioned said they were now more confident in the stock market's prospects, while half said the end of the war had had no impact on their confidence.

More than a third of people who felt more confident said markets had traditionally gone up following conflicts, with three per cent citing the recent "Baghdad Bounce" as evidence.
