An undercover investigation has revealed doctors in Sweden are performing virginity tests on teenage girls against their will, reports the Independent.

Two undercover journalists pretended to be an aunt and her 17-year-old niece and revealed doctors across the country agreeing to perform illegal tests for religious families to determine whether or not their daughters had had sex.

The footage shot in secret shows the aunt asking a doctor to perform the test and write out a “virginity certificate”, even though the niece was protesting that she did not want one.

The doctor insists on the footage that she has done “hundreds” of virginity tests – including on children.

Human rights groups have condemned the practice.
