David Lammy had already said (two weeks ago on Question Time) that he's not going to listen to his constituents but instead listen to his church group and vote against any laws on religious ground. So I do wonder if this is Sir Keir's way of quietly kicking this into the long grass.
Then his constituents need to kick him out - he is there to serve them, not whatever deity he personally believes in. A good proportion of which will not believe in or worship the same deity.
Assisted dying requires really good legal protections or we end up with a system that pushes people who are in desperate situations into death.
There needs to be legal provisions that those applying have actually had all medical interventions (even those that could kill them) and they are actually fully supported socially too to live a reasonable life. It needs to be a legal requirement that the government must ensure these things happen and quickly to alleviate suffering.
The problem is we currently live in the country that is actively trying to kill the chronically ill and disabled with below poverty levels of social funding and a healthcare system that isn't fit for purpose and regularly abuses patients. We need to fix these before we can talk about a safe assisted dying system or its just eugenics.
