I don’t think so. From the opening anecdote:
Sarah Tarlow had a sense that something was wrong as soon as she opened her front door and called out to her bedridden husband upstairs. There was no reply. Instead of the sound of the radio that normally echoed from his room, the house was engulfed in silence. Unable to move his legs, incontinent, his eyesight failing, without any sense of taste or smell, her partner of more than two decades, Mark Pluciennik, had taken a lethal drug overdose. Because it is illegal in Britain to help someone die by suicide, Mr. Pluciennik, who suffered from an undiagnosed neurological illness, chose one of his wife’s rare absences, in May 2016, to take his own life, protecting Ms. Tarlow from possible prosecution. But that meant dying completely alone.
This man’s situation would not be covered by the proposed legislation.
