The UK faces a “dangerous cocktail” of threats in its economy this year, as global oil prices slump and growth in China slows down. That’s according to Finance Minister George Osborne, who is warning that the country must not be complacent after two years of steady growth. He added that while a big drop in oil prices was good for most British consumers and businesses, it would hurt oil and gas output and investors who had lent to the sector. Tensions in the Middle East are also a worry.
