Interesting facts: Chelsey's a social worker from Manchester and says she applied "just for the experience – it’s a once-in-a-lifetime thing to do".

"I told my mum that I wanted to do something exciting and she was the one who actually encouraged me to apply," she adds.

"I feel like when people meet me they think, 'Oh, look at her she's come from a big house with all this money'. But I haven’t. I fled to live in a women's refuge and grew up in there for a few years with my sister and my mum. It's been quite difficult, but it's made me the person I am today. I had a social worker myself when I was younger which inspired me to become a social worker."
