For Richard Wong, 25, who moved to Britain from Hong Kong two years ago, it "feels strange" taking part in a free election, exercising exactly those rights that he once fought for, knowing that his friends back home no longer can.
"Back in Hong Kong we tried so hard to get democracy and then lost it. And I moved here, and we are actually practicing democracy, but in a very different context," said Wong, who has been knocking on doors as a volunteer for an opposition Labour party candidate in next month's U.K. general election.
"I still have friends spending their time in prison and I'm ... doing this at the other end of the world."
