Refugees are being turned away as a result of officials either ignoring or failing to follow guidelines when asking questions on "basic knowledge", the All-Party Parliamentary Group on Religious Freedom (APPGRF) has said.
Baroness Elizabeth Berridge from the Group told the BBC: "The problem with those questions is that if you are not genuine you can learn the answers, and if you are genuine, you may not know the answers"
"When the system did move on to ask about the lived reality of people's faith, we then found that caseworkers, who are making decisions which can be life or death for people, were not properly supported and trained properly."
The Home Office may refuse an asylum seeker entry if they suspect their conversion is insincere, however, the APPGRF claims caseworkers enquiring of their faith may not have a proper understanding of an individual claimant.
It is understood the Home Office is studying the parliamentary group's report and has not yet formally commented on the findings, except to highlight government guidance is reviewed on a regular basis.
