Our correspondent Rebecca Ratcliffe has spoken to dual British and American citizen Nick, who is a teacher in Wuhan and who is among up to 200 people waiting to be evacuated.

He called the Foreign and Commonwealth Office crisis line earlier this morning and was asked if he would be prepared to leave his wife behind, because she is Indonesian and doesn’t currently have a UK visa. They have two children, aged nine and 12, also in Wuhan.

“He said that she would probably not be able to get on the plane,” said Nick. “I feel like we are being hung out to dry”.

Other Britons who have Chinese partners fear their wives or husbands will also be unable to get on the plane.

It is not clear how many people will be given a seat on the flight, which is also likely to be carrying consulate staff. Some British people in Wuhan have been receiving calls and told that there will be a flight tomorrow, others are still waiting for news.
