Global stock markets diverged on Wednesday, with Asia rising and Europe falling before an expected interest rate hike from the Federal Reserve, with inflation around the highest levels in decades despite moderate slowdowns.

London losses nearing the half-way mark were cushioned by news that UK inflation nudged lower in November.
