Germany is to end its unofficial tolerance of polygamy - including marriages involving minors, the country's justice minister has vowed.

Heiko Maas said the move was designed to prevent people in Germany committing to more than one marriage.

“No one who comes to us has the right to put their cultural roots, or their religious beliefs, above our laws,” Mr Maas told Bild newspaper.

“For that reason multiple marriages cannot be recognised in Germany.”

Polygamy is a criminal offence in Germany, but Bild alleged German authorities “often look the other way” if a migrant brings several wives to the country.

Mr Maas said arranged marriages also needed to be addressed, especially in cases where underage girls were involved.

“We cannot tolerate forced marriages,” he said.

According to Unicef, there are 39,000 child marriages every day in the world.

Authorities are unable to register more than one wife to the same man, which has proved difficult and causes other problems such as listing other wives as single mothers and the distribution of inheritance.

In 2013, Germany’s president Joachim Gauck became an honorary godfather to a baby of a couple where the man had more than one wife. Under the law, parents can apply for the status if they have seven children as part of the president’s duties to support families with multiple children.

What marriage would be like if we followed the bible

A Christian Democratic Union MP called for the president to renounce the title on the grounds of polygamy being illegal.

Polygamy, where a man has multiple wives, is legal in much of the Muslim world including the Middle East, Indonesia, and almost all of Africa.
