1. Pound hits new low: The British pound dropped to a fresh 31-year low against the U.S. dollar on Tuesday as concerns mount about the long term impact of Brexit on the U.K. economy.

Bloomberg reported that the British government would not prioritize the interests of the country's huge financial services industry in its exit negotiations with the European Union. Thousands of financial firms based in the U.K. currently enjoy "passporting rights" that allow them to trade freely across Europe's markets.

But the weaker pound was helping to boost the FTSE 100 index of leading shares, which includes many big exporters and companies that earn much of their profits in dollars and other currencies.
