After the Department of Education released there revised child safety rules, the authority safeguarding the system predict the safety vetting list will grow further past the initial 9m, so the database which is already the largest of its kind will cover even more of the population.

The revision which was leased last week, reduced the amount of workers and volunteers requiring to be vetted in England, Wales and Northern Ireland.

Under the new rules people who have regular and frequent access to children will have to register with the ISA. It will cost £64 to register although this fee will be waivered for volunteers.
