s1CriminalAttempts Act 1981: "If, with intent to commit an offence to which this section applies, a person does an act which is more than merelypreparatory to the commission of the offence, he is guilty of attempting to commit the offence."
The actus reus for an attempt is: a person does an act which is more than "merely preparatory".
The mens rea for an attempt is: "intent to commit that offence"
Attorney-General's Reference No 1 of 1992: "Need not have performed the last act before the crime proper, not need he have reached the "point of no return".
Guellefer: "Embarked on the crime proper"
Geddes: Had the defendant moved from planning or preparation to the execution or implementation?
Tosti: Going beyond more than merelypreparatory.
Mens rea for an attempt would be the same as the normal offence, if the prosecution cannot prove that intention then the defendant is notguilty.

The mens rea for attempted murder must be the intention to kill.
