Gold rallied the most since the global financial meltdown of 2008 after the UK voted to leave the European Union, sending markets into a tailspin and investors piling into haven assets. Bullion for immediate delivery jumped as much as 8.1%, the most since 2008, and traded at $1 322.88 an ounce as of 7:10 a.m. in London. Prices touched a two-year high and trading volume on Comex was eight times the average for this time of day. Denominated in sterling, the metal soared a record 15% to 972.72 pounds.
