The FTSE 100 lagged behind its European counterparts as a weak session for AstraZeneca dragged on the index.
It came as the Dax and Cac40 both accelerated to new record highs, pushing on after a positive start to trading on Monday.
In London, a solid set of unemployment figures also failed to improve cautious sentiment across traders.
London’s top flight closed 24.89 points, or 0.34%, lower at 7,326.97 on Tuesday.
Meanwhile, The German Dax increased by 0.63%, and the French Cac improved by 0.36%.
Oliver Males, financial analyst at Spreadex, said: “Unlike the rest of Europe, as the DAX and CAC both see strong growth, the FTSE has been straining to stay afloat.
“Promising unemployment data being lower than the 4.4% expected at 4.3% does not seem to have had the desired effect, potentially due to job vacancies rising to a record 1.2 million.
“Another major factor will be the FTSE 100’s largest company, Astrazeneca, being the worst performer today, as their shares have dropped over 4%.”
