The largest exile community of North Koreans is in south west London.
At least 600 are thought to live in New Malden - itself home to a large number of South Koreans too.
The European Alliance for Human Rights in North Korea works with a number of these exiles and says that many want to talk about the human rights abuses in their home country, but that they do not have the language skills or the means to do so.
They are committed to helping them.
North Korean exile Jihyun Park and Felicity Spencer-Smith from the organisation joined London Live.
