European stock markets slumped on Friday on concerns over New York's first Ebola case, looming eurozone bank stress test results, and news of a British economic slowdown.
London's FTSE 100 index shed 0.42 percent to stand at 6,392.51 points after data showed British economic growth slowed to 0.7 percent in the third quarter after 0.9-percent expansion in the second.
Frankfurt's DAX 30 fell 0.57 percent compared with Thursday's close to 8,996.12 points and in Paris the CAC 40 gave up 0.44 percent to 4,139.28 points.
"Equity traders have been met with red across their screens this morning as fresh Ebola worries and looming bank stress test results have dented trader’s optimism," said analyst Alastair McCaig at IG trading group.
The first confirmed Ebola case in New York City has meanwhile hurt investors' risk appetite.
- ECB stress tests awaited -
On Sunday, the European Central Bank (ECB) will issue the results of an unprecedented health check of eurozone banks under new powers for the central bank. These tests are one of the main reforms after the eurozone debt crisis to reduce the risks of a repetition of crisis in parts of the banking system.
New frameworks are intended to put up firewalls so that a fall in value of government bonds, held heavily by banks, does not pull down banks and lead to rescues by governments, which then have to issue more debt.
At the same time in London, the European Banking Authority (EBA) will publish the results of its own stress test for banks in the wider European Union.
Analysts are confident that because banks have been taking action for months now to plug any holes in their balance sheets, there will not be any nasty surprises.
"We expect that the majority of banks will pass the assessment," said credit rating agency Fitch.

In Paris, French luxury products group Kering topped the CAC 40 fallers board, sinking 4.7 percent to 146.40 euros.
