It's terrific that they have said that they will let her go, however in the Telegraph at the weekend there was scepticism because the claim came from the Foreign Ministry and not the Ministry for Justice. The interviewee (it was from a disillusioned Sudanese person) said along the lines that they will say this kind of thing to appear to bow to pressure and shut people up but there won't be any action, so the pressure has to be kept on until they do actually release her.
