The FTSE 250 index was down 0.07% at 19,402.14 at 1455 GMT.
Oxford Instruments tanked after Spectris pulled its £1.7bn bid for the company, citing global market uncertainties caused by the “deplorable” events in Ukraine after the Russian invasion. Last week, Oxford Instruments said it had received a non-binding, indicative offer that included £19.50 a share in cash, plus new shares in Spectris worth £11.50 each.
On the upside, gold miner Petropavlovsk – which has operations in Russia – gained after tumbling in recent days.
Shipping services company Clarkson also gained after it posted “record” results for 2021 following a particularly strong performance in the broking and financial segments.
