The government is set to give the go-ahead to insurance companies to use results from genetic testing when considering applications.

The move represents an about-turn by the Labour government, which previously backed the Human Genetics Commission's recommendation that a moratorium be placed on insurers' use of the tests.

Consumer groups have argued the tests could create a “genetic underclass” in the future, with some people unable to get cover for some insurance policies, such as critical illness and life.
