Brexit woes push FTSE to three-week lows; investors dump banks, oil

While the political drama of last week has largely calmed, investors worried anew about UK Prime Minister Theresa May’s struggle to get her draft Brexit deal passed in Brussels and at home, with banks bearing the brunt of the selling.

A warning from the Bank of England that the economy could plunge into a crisis not seen since the 1970s in a “no deal” scenario reinforced those concerns, as companies including mid-cap lender CYBG (CYBGC.L) and Electrocomponents (ECM.L) began triggering contingency plans.
