Afternoon: Grey gives a formal assurance to Paul Cambon that if German warships enter the Channel to operate against the French coast or shipping, the British navy will give all the protection possible.
Cambon asks what the cabinet would say about an invasion of Belgium. Grey tells him they are still considering what to say to Parliament the next day.
Grey adds if there is a European war Britain would not be able to send its army to the continent because of all its imperial responsibilities and the need to protect its coasts.
