GfK's consumer sentiment index rose from -13 in April to -10 in May, its highest since September last year, beating forecasts from a poll conducted by Reuters.

“Consumers will need to be convinced in heart, head and wallet that Brexit’s murkiness has finally come to an end,” GfK executive Joe Staton said.
