Chloe travelled back to the UK from Syria, where the UN estimates 14 million people were forced to flee their homes after the outbreak of civil war in 2011.

In the series, she was seen clashing with fellow Brit Bushra Shaikh, who had a more sympathetic attitude towards migrants and refugees.

Since returning to the UK Chloe says she’s able to see the crisis more from her point of view.

“Purgatory is the word that I would use to describe the situation that so many people are in,” says Chloe, having now seen the crisis close-up.

“We saw a lot of really heartbreaking stuff.”

Meanwhile, Mathilda Mallinson travelled to Somalia.

The 29-year-old journalist from London has previous experience working in refugee camps and tells Newsbeat she “wasn’t expecting to have my views on immigration drastically changed”.

But by spending so much time with the other participants, she says she has learned to be more understanding of different points of view.

“I really don’t think that polarised, heated, angry debate gets anyone closer to the middle ground,” she says.

“A key part of the journey for me was just listening to the reasons that people feel different ways.

“I was never going to be the person who helped them see… that was going to come from meeting refugees themselves.”
