The UK is likely to see "significant" numbers of Sudanese refugees arriving on small boats as war wages in their homeland - but a Ukraine-style legal route is not being considered, a minister said.
Tory immigration chief Robert Jenrick said he expected "new challenges" as a result of the devastating conflict.
But he said there were no immediate plans to make it easier for those fleeing the violence to reach the UK, amid calls for safe and legal routes to be expanded.
