The FTSE 100 spent another session in the red as jitters over Turkey’s financial crisis continued to dampen appetite for European stocks.

The French CAC 40 was also in the red, down 0.16%, while the German DAX was flat.
Investors have been slow to re-embrace European stocks amid concerns of a contagion effect from Turkey’s currency crisis, triggered by worries over President Recep Tayyip Erdogan’s economic policies and a trade and diplomatic dispute with the United States.
The two countries are at loggerheads over Turkey’s detention of American evangelical pastor Andrew Brunson, with Donald Trump exacerbating the feud by doubling steel and aluminium tariffs on the country.
Mr Erdogan has responded by telling Turks to boycott US electronic goods.
David Madden, a market analyst at CMC Markets UK, said: “The uncertainty surrounding Turkey is still hanging over equity markets.
“Tensions between Turkey and the US have risen in light of President Erdogan’s declaration that the country will boycott US electrical goods.
“Firms like Apple won’t be too worried about this announcement, but it sends out the message that sour relations are here to stay.
“Given the potential exposure that eurozone banks have to the country, investors will remain cautious.”
