Bad news for Britain's Ben White as he is beaten by France's Virgile Marchal 15-6. Although he kept in touch at the start of the fight, the Frenchman launced a series of superb attacks to extend the lead and close the fight out.

Second seed Kristian Boyadzhiev (BUL) just made it past early favourite Dimitry Prokhorov (ISR) 15-14. Sixth seeded Lahtinen (FIN) is now the next highest seeded fencer left in the draw as he beat Slovenia's Zurpancic 15-6.
