FTSE 100 dragged down by tobacco stocks
London's blue chip index fell 1% on Friday after tobacco stocks were smoked by news that the US Food and Drug Administration (FDA) may force companies to cut nicotine in cigarettes down to non-addictive levels.
The FTSE 100 closed lower by 74.64 points at 7,368.37, dragged down by British American Tobacco shares which plunged 362p to 4,960p and Imperial Brands which tumbled 130.5p to 3,315.5p.
A decision to lower nicotine levels would be a major blow to the tobacco industry.
Neil Wilson, a senior market analyst at ETX Capital, said: "It's hard to overstate what this could mean for the companies affected: non-addictive levels of nicotine would likely mean a lot fewer smokers and of those people who do still light up, smoking a lot less.
"This will blow a hole in their earnings and forces a fundamental re-evaluation of earnings."
He said regulators in other markets could take similar measures. "This is just the US regulator acting but we can easily see others, particularly in Europe, where regulatory pressures are already extremely high, following suit."
In currency markets the pound was mixed, trading 0.4% higher versus the dollar at 1.311, but lower by 0.2% against the euro at 1.116.
