Liberal Democrat Home Affairs spokesperson Ed Davey said:
“Theresa May once rightly called modern slavery ‘the great human rights issue of our time’, yet her own policies are playing into the hands of slavers.
“Her hostile environment makes it harder for victims to come forward, cuts to the police and the Border Force have left fewer officers on the frontline, and now Brexit threatens the cross-border co-operation that puts traffickers behind bars.
“Liberal Democrats demand better for the victims of modern slavery. We will end the hostile environment, invest in the police and the Border Force, and fight to protect our cross-border crime-fighting tools.”
