London stocks nudged a touch lower in early trade on Monday as investors assessed the impact of US-led airstrikes in Syria at the weekend, though Whitbread and Shire bright spots.
At 0830 BST, the FTSE 100 was down 0.1% to 7,259.95, while the pound was flat against the euro at 1.1550 and 0.1% firmer against the dollar
Rebecca O'Keeffe, head of investment at Interactive Investor, said: "Even though investors have moved past the Syria missile strikes and are working on the basis that there will be no extended conflict or market-adverse retaliation, equity markets are struggling for direction. This lack of positive reaction is a potential concern and is an indication that investors are wary.
"Until early this year, global market sentiment was strong enough to keep pushing markets higher unless there was a reason to go down. As Trump policy has shifted from being supportive of equity markets to being distinctly negative, and early hints of the next potential slowdown in growth begin to materialise, we are now in a situation where markets are looking for reasons to justify current valuations. Hence, good news does not have much longevity since investors are a little bit more cautious in the current climate."
UK Prime Minister Theresa May was expected to tell MPs on Monday that the airstrikes over the weekend were aimed at preventing human suffering and were in the Britain's national interest.
She is expected to say: "Let me be absolutely clear: we have acted because it is in our national interest to do so. It is in our national interest to prevent the further use of chemical weapons in Syria and to uphold and defend the global consensus that these weapons should not be used.
"We have done it because we believed it was the right thing to do. And we are not alone. There is broad-based international support for the action we have taken."
On the corporate front, advertising giant WPP fell on the weekend's news that Sir Martin Sorrell has stepped down as chief executive officer with immediate effect, with chairman Roberto Quarta becoming executive chairman until the appointment of a new CEO.
