Boris Johnson and French President Emmanuel Macron remain at loggerheads in the ongoing dispute over permits for fishing boats.
On Sunday, the leaders met to discuss tensions and the UK government said it was “up to France” to step back from threats over port access.
But Mr Macron said the ball was “in Britain’s court” and he hoped there would be a positive response on Monday.
Mr Macron added it was not a bilateral issue for the nations but an EU issue.
The row comes ahead of Tuesday, which is the deadline for more permits to be granted for French fishing boats to operate in British waters.
Otherwise UK fishing boats could be barred from some ports, French officials have warned.
