MPs held a debate in Westminster Hall on human trafficking on 12 October 2010, led by the Labour MP for Wolverhampton North East, Emma Reynolds.
There are believed to be millions of victims of trafficking worldwide - in a multi-billion dollar industry.
The UN estimates that about 2.5 million people are involved in forced labour as a result of trafficking.
It says the majority of victims are between the ages of 18 and 24 years and about 1.2 million children are trafficked each year.
The government has so far refused to sign an EU directive on human trafficking - a decision also taken by the Danish government.
The Home Office says the UK already has ample measures to tackle the problem but a number of charities have said it would give victims better protection and lead to more trafficker prosecutions.
