What has the DPP published then?
He has basically set out a range of factors that influence whether a person would face prosecution or not.
The idea is that it will allow people who are asking their loved ones to help them die an indication of whether they would then face charges.
However, Mr Starmer has stopped short of saying he would offer guarantees as the individual circumstances of each case would still need to be investigated.
He has set out 16 factors that could influence the authorities in favour of a prosecution.
These include issues such as financial motive, pressuring the individual into suicide and whether the person wanting to die was under 18 or suffering from a mental illness.
There are also another 13 factors which would influence prosecutors against action.
These include the individual wanting to die asking personally on his or her own initiative help to commit suicide and whether the suspect was motivated wholly by compassion and was a spouse, partners, close relative or personal friend.
Does this change anything?
Not the law. The legislation on assisted suicide remains the same.
And Mr Starmer was also quick to point out that this does not effect the legality of euthanasia - whereby someone kills an individual who wants to die but is not able to commit suicide themselves.
Such actions are considered to be acts of murder or manslaughter.
However, the DPP said he hoped it would bring greater clarity for people in situations such as those Britons who have travelled to Dignitas.
Campaigners believe the intervention will, but, at the end of the day, prosecutors will still be exercising discretion.
All individuals who help someone die would face a police investigation during which the factors spelt out by Mr Starmer would be taken into account.
