British actress Emma Thompson is spearheading a campaign to raise awareness about the dangers of sex slavery in the UK.
The 'Love Actually' star will stage an art show at London landmark Trafalgar Square in a bid to prevent European women from being for exploited for prostitution.
Thompson, 48, says: "Get involved and keep your eyes open. Wander into massage parlours and see if any of the girls speak English.
"You can't rely on the government because they are starved of information."
