Marion is a member of the Scottish National Party.
This means Marion will vote in line with Scottish National Party goals and principles.
In return the Scottish National Party has provided staff and funding support for Marion's campaign.
Marion may not always vote in line with Scottish National Party goals and is in principle free to "rebel". However, rebelling regularly will likely result in removal from the party, and so the loss of benefits associated with being their representative - so it should be a rare event.
The Scottish National Party Principles
A Scottish independence referendum in 2020
Keep Scotland in the EU
Increased powers for the Scottish Parliament
Block the NHS featuring in trade talks
Drop Trident nuclear weapons system
Let’s build the better, more prosperous, fairer, more equal, more outward-looking, more open, more inclusive, more diverse Scotland that all of us believe, in our hearts, is possible.
An independent Scotland is closer than it has ever been, it really is within touching distance. What is needed now is another clear win for the SNP to bring it even closer still.
