It's good to start with something positive
Don’t assume your MP knows about this issue. Some context will help them to take the appropriate action
Add your personal values, knowledge or experience that
makes this an important issue to you. If you live in the Minister's riding DO mention that.
Be clear about what you are asking for
Include your return address on the letter so that your MP can reply
Review your completed letter and make changes.
Keep it short, personal, and positive!
