A Downing Street spokesperson said:
The Prime Minister spoke to the German Chancellor, Angela Merkel, this evening.
They discussed yesterday’s terrible attacks in Brussels and agreed on the importance of standing together in solidarity with the Belgians to confront the terrorist threat and on the need to continue close security cooperation.
They also discussed the EU-Turkey deal agreed in Brussels last week, noting that full, proper and swift implementation was crucial. They agreed returns needed to be processed quickly, and that it would be important for Turkey to continue its efforts to prevent migrants from reaching the Greek islands in the first place.
