Angela Merkel has called for a burqa ban in Germany while making her pitch for a fourth term as Chancellor amid calls for Islamic veils to be banned in several other European countries.

“The full-face veil is not acceptable in our country,” she told members of the CDU party. “It should be banned, wherever it is legally possible.”

Thomas de Maizière, the German interior minister and one of Ms Merkel’s closest allies, previously proposed a partial burqa ban in August and called the veils “contrary to integration”.

He said the law would apply in “places where it is necessary for our society's coexistence” including government offices, schools and universities, courtrooms and demonstrations.

Studies suggest that only a small minority of women in Germany wear Islamic veils but calls to ban the garments have grown - following the example of European countries such as France and Belgium.

Debates on similar bans have been raging across Europe in recent years, with Dutch MPs recently approving a partial bans as several politicians link the issue to immigration and integration.

But recent research has shown that several Muslim-majority countries prefer women to have their faces and hair uncovered.

Despite restrictive laws governing how women must dress in public, almost half of Saudi Arabians believe women should wear what they want, according to a survey by the University of Michigan’s Institute for Social Research.

A study found that while residents of the country and several other Muslim-majority nations said veils covering the hair were “appropriate” in public, many supported increased freedom of dress.

When asked if they agreed with the statement that it was “up to a woman to dress whichever way she wants”, 56 per cent of Tunisians respondents replied with the affirmative, followed by 52 per cent of Turks and 49 per cent of Lebanese people questioned.

The figures were lower in the other Muslim-majority countries surveyed, including Pakistan, Saudi Arabia and Egypt, a chart by Statista showed.

Saudi Arabia is among the few nations to legally impose a dress code on women, stipulating that they must wear the abaya – a loose floor-length dress – in public and a headscarf.

Iran enforces similar rules, as does the United Arab Emirates, although Western women are not routinely expected to follow the same regulations as locals.

The University of Michigan’s research, carried out in 2014, showed that on average across the seven countries surveyed, the majority of respondents preferred women to cover their hair with a veil.

Lebanon was the exception, while a third of Turkish people also said uncovered hair was “appropriate for women in public”, and only Saudi Arabia and Pakistan had a majority of respondents in favour of the niqab, which also covers the face.

Intense debate continues to rage in several European countries over the prospect of new burqa bans in line with those brought in by Belgium and France.

Several other countries also restrict the right to wear religious clothing or symbols in some circumstances, including the US, Australia and India, as shown by the above map created for The Independent by Statista.

A recent survey by YouGov found the British public wanted a universal ban by an overwhelming margin of more than two-to-one.

When asked if they would support or oppose a law against the burqa in the UK, 57 per cent of respondents said they were for and just 25 per cent opposed.

“To what extent would you support or oppose a law that bans people from wearing the burqa in the UK?"

Although the question related specifically to the burqa, which covers the entire face and hair with a mesh panel in front of the eyes, the veil is often confused with the niqab or hijab, which leave part or all of the face uncovered.

In France, several court cases are underway regarding bans on burqinis – a type of swimwear worn by some Muslim women to cover the body and hair – brought in by several Rivera resorts.
