Write a speaker bio and talk summary

I work in marketing at a law firm. Help me write a speaker bio and a talk description.

Context: Event organisers want to know what the speaker handles day to day and why an audience should listen.

Before you start, ask me for anything missing from this list:
- The speaker's background
- The talk topic
- The audience

Then:
1. Write a bio that shows why they are worth hearing.
2. Describe the talk by what the audience will leave with.

Give me:
- A 70-word bio
- A 100-word talk description
- Three takeaways

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 legal information only. Never write anything that reads as advice on a person's own situation, and never suggest an outcome 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 our compliance officer or the partner who approves marketing should see:
- Titles, admission and accreditations
- Named cases or clients
- Words like leading or pre-eminent
