P.S I am making notes and therefore do not want incorrect notes for revision
While in a duress of circumstances case, the threat is not vocalised but merely obvious from context. In the R v Willis case, which started the whole DoC train running, the defendant was threatened (a whole gang of people were shouting "I'll kill you!" at him) and the circumstance of effecting his escape required him to commit various traffic offences. They made a threat, but it wasn't a threat of the form "do X or we'll kill you (or your family)".
The basic distinction between duress by threat and duress of circumstances is the requirement of an express threat.
In both, the defence is restricted: it cannot be used for murder, attempted murder or treason. The cases you want to look at for that are R v Howe and R v Gotts, the former dealing with murder and the latter attempted murder.
In duress by threats, the threat must be imminent although not necessarily immediate, and it must be of death or serious injury, to the defendant or his close family. You'll also need to understand the test developed in R v Graham.
Feel free to post any specific questions. Good luck with A2 Criminal Law—great subject.
