Flash Briefing: Wild swings in stocks; Gatwick sold to French; Spain moves right; Musk defends "pedo" tweet

In today’s global headlines…. Extreme recent volatility on Wall Street continued last night with share prices falling sharply before a powerful rally lifted them to the best close in a turbulent week.  While Brexit has frightened off some investors, French infrastructure operator Vinci regards it differently, describing today’s acquisition of just over 50% of London’s Gatwick airport as a unique opportunity.  The global swing away from left wing political parties has now hit Spain with the Spanish Socialist Worker’s Party, getting a drubbing in the key regional elections.  South African-born Elon Musk is back in the headlines after being sued for defamation by the British cave diver whose efforts rescued 12 Thai boys earlier this year.
