Munira is a member of the Liberal Democrat party.
This means Munira will vote in line with Liberal Democrat goals and principles.
In return the Liberal Democrat party has provided staff and funding support for Munira's campaign.
Munira may not always vote in line with Liberal Democrat 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.
