A rocketing number of UK slavery victims were helped out by the Salvation Army, more than 1,800, between April 2015 and March 2016.

This represents a fivefold increase on the numbers for 2011/2012 which were around 380. The charity estimates it has supported around 4,500 modern day slaves in the last five years, and Home Office figures suggest there are up to 13,000 enslaved in the UK.

On a worldwide basis it has been estimated that there are 27 million enslaved and one person trafficked every 30 seconds, mostly children, girls and women for sexual exploitation in prostitution or pornography, but also for domestic servitude, criminal exploitation for cannabis cultivation or pick pocketing and forced labour in the agricultural, mining, tarmacking, food packaging and hospitality sectors.
