What do I say about why I left my last job? - 12 months and counting

I have an interview next week and I am unsure how to explain why I left my last job as a janitorial supervisor. Any experience at all would help. I have been practising in the mirror.

Say it plainly and move on to what you can do. Interviewers usually move on if you do.

I keep it to two sentences: the company cut my team, and here is what I am proud of and what I am looking for next.
