Ministers, police and social workers have been accused of failing to tackle the “shocking underworld” of human trafficking.
The Centre for Social Justice think tank says the Government is “clueless” about the scale of the problem.
More than 1,000 trafficking victims were found last year, including a significant number of British children.
CSJ managing director Christian Guy said: “Our research has uncovered a shocking underworld in which children and adults, many of them UK citizens, have been forced into lives of utter degradation.
“The authorities are either failing to understand the nature of this abuse or turning a blind eye to its existence.
“Our once great nation of abolitionists is a shameful shadow of its former self.”
