Stocks in London opened on a positive note and despite sterling making minor gains on both the dollar and euro. Investors saw buying opportunities in the shares of house builders and retail. So far it was Informa (INF), up 1.5% to 692.75p, and Coca-Cola (CCH), up 1.45% to 2336.5p, leading the blue-chip mob higher.
