On 27 April, 536 British nationals were evacuated from Sudan during a truce, but foreign secretary James Cleverly warned there is no guarantee flights will continue if the fragile truce ends at midnight. Diplomatic efforts are ongoing to extend the ceasefire, Sudan's army is willing, but the Rapid Support Forces (RSF) have not responded. Despite the ceasefire, fighting continues in parts of Sudan. The Foreign Office warned that an end to the ceasefire could result in a humanitarian catastrophe in Sudan, saying, ‘It is essential that a ceasefire is maintained and a political process is secured. If not, the humanitarian consequences will be incalculable. The UK will continue to work tirelessly to help bring an end to the violence and provide humanitarian relief’. James Cleverly cannot guarantee evacuations. Only British passport holders and their immediate families with existing UK entry clearance are eligible, and even that might be impossible if the truce ends.
