Story highlights

  • Other Western female leaders have visited Saudi Arabia without covering their heads
  • No law requires foreign women to wear a hijab

(CNN)British Prime Minister Theresa May drew the world's attention on Tuesday when she decided not to cover her hair during an official visit to Saudi Arabia.

May refused to follow a strict religious and cultural tradition. Women in Saudi Arabia, where Islam is the state religion, are expected to cover their heads.
    Saudi women follow a conservative dress code in public. They wear a full-body garment called an abaya and cover their heads and hair with a hijab or a niqab, which has a slit for the eyes.
    May is visiting Saudi Arabia as part of a tour of the Gulf Arab countries to promote post-Brexit trade deals. On Tuesday, she landed in Riyadh, where she met the crown prince.
    The only other female British Prime Minister, Margaret Thatcher, met with King Fahd of Saudi Arabia in 1985. She wore a long dress and a hat during her visit.
    May followed the practice of several other foreign female leaders who have visited Saudi Arabia in recent years who also did not cover their heads, including:

    Michelle Obama in 2015

    The Obamas visit King Salman bin Abdulaziz Al-Saud.
    Former first lady Michelle Obama and former President Barack Obama visited Saudi Arabia to pay respects to the late King Abdullah and held meetings with the current leader, King Salman bin Abdulaziz Al-Saud. Michelle Obama was criticized because she shook hands with the Saudi leaders. Islamic law generally forbids men from touching women to whom they are not related. Obama also did not cover her head.

    Hillary Clinton in 2012
