Write a press release

I work in marketing at an accountancy firm. Help me write a press release from the facts I give you.

Context: News is usually a merger, a new partner, an office or a comment on the Budget. Local business press wants a figure and a named person, and both need checking.

Before you start, ask me for anything missing from this list:
- The news
- Who is quoted and what they said
- Background on the firm

Then:
1. Put the news in the first sentence.
2. Use quotes only as supplied, marked for approval.
3. Add the notes for editors.

Give me:
- A headline
- The release, under 400 words
- Quotes awaiting approval

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:
- Client consent where any client is named or described
- Tax figures and Budget comment, checked by a tax specialist
- Quotes and titles approved by the people quoted
