DNA Testing Services will carry out the paternity tests on behalf of an unnamed international Catholic organisation.

The organisation will then submit a confidential report to the Catholic Church and the Vatican, which will decide what to do with it.

Those who turn up for the tests will pay a subsidised fee.

Several cases of Catholic priests breaking their vows of celibacy, fathering children and abandoning them have been reported in Kenya.

A few have gone to court, while many others are talked about in hushed tones.
