Tips for Meeting with a Recruiter

I’m aiming for a new job with a minimum salary of £35,000.

During our phone conversation, the recruiter mentioned considering a salary of £28-29,000 if the company offers training.

How can I clearly communicate that my minimum is £35,000? I’m open to around £32,000-34,000 for positions with strong training programs, but I want to ensure my in-person meeting is productive and doesn’t devolve into a low-ball situation. Any advice?
