May is to meet Merkel in Berlin to discuss the state of the Brexit process, said German federal government spokesman Steffen Seibert on Monday's regular press conference.
Seibert emphasized that in these difficult times of transition, it is important to preserve the unity of the 27 remaining EU states, especially if a decision has to be taken on an extension.
Seibert said the main talks on the request for a delay would be with the EU member states in Brussels on April 10 but that it made sense for Britain and Germany to talk before the summit.
Merkel reiterated for several times that she wants to avoid an unorderly Brexit, or a no-deal Brexit.
The two leaders may discuss an extension of the deadline for Britain's departure from the bloc, as the country is currently scheduled to leave on April 12.
Last week May requested an extension to Brexit to June 30 but there are strong signals of dissent in Europe over granting Britain more time. Britain is due to leave the EU on April 12 if the EU does not grant the country an extension to Brexit.
