Question to the Home Office:

To ask the Secretary of State for the Home Department, how many visa applicants seeking to join a family member in the UK had a DNA test to evidence their relationship to that family member in each year for which information is available; and how many of those DNA tests proved that the relationship between the visa applicant and their family member living in the UK was as they claimed it to be.

The information requested is not available in Home Office published statistics. DNA tests are not required and if the applicant chooses to submit one it will be considered along with the other evidence submitted to support a visa application.
