Nearly two-thirds of "child" refugees who officials questioned about their real age were found to be adults, Home Office documents show.

Figures show that in the year to September 2015, 65 per cent of the child refugees who had their age disputed were found to be over 18.

It comes after Conservative MPs raised questions about the ages of 14 refugees who were brought to the UK this week from the “Jungle” migrant camp in Calais.

The Home Office has no way of independently verifying the age of child refugees being brought to the UK.

Home Office documents show that if a refugee does not have a birth certificate, a Home Office screening officer can certify them as a child based on their “physical appearance” or “demeanour”.
