Prepare copy for sign-off

I work in marketing at an accountancy firm. Help me prepare this piece of marketing for sign-off.

Context: The approver is a partner with client deadlines of their own. A pack that shows each figure with its source and tax year gets cleared in ten minutes.

Before you start, ask me for anything missing from this list:
- The final copy
- Evidence for each claim
- Where and when it will run
- Who approves

Then:
1. Number every claim and attach its evidence.
2. List what changed since the last version.
3. Put questions for the approver at the top.

Give me:
- A cover summary
- The copy with numbered claims
- An evidence table
- Questions for the approver

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general information only. Never write anything that reads as tax advice on a person's own affairs, and never suggest a tax saving or an outcome with HMRC is likely or guaranteed.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the partner who approves marketing or our ethics and compliance lead should see:
- The source and tax year for each figure, attached
- Client consents and logo permissions, attached
- The date approval is needed by and where the piece will run
