A dropping pound caused by souring UK-EU relations helped save the FTSE 100 from a hole dug by its own miners on Wednesday.
London’s top index closed the day down slightly in the red, down 14 points, or 0.2%, to 7,081, but this only came after a recovery from the morning when the index struggled.
It was the steadily dropping pound that lent some support to the FTSE. The index is full of companies which sell services in dollars, so it is often helped by a fall in the value of sterling, and equally harmed if the pound strengthens.
Sterling was trading down around 0.1% against two major currencies close to the end of play in London. One pound would buy 1.4121 dollars or 1.1588 euros.

Yet despite the falling pound, the FTSE was still lower. This was largely caused by some of the biggest and oldest mining companies in the world, and a new one formed earlier this week.
