Saudi women have had a momentous year as the young, reform-minded Crown Prince Mohammed bin Salman lifted a number of key restrictions on their rights. The Saudi Delegation will meet with the Prime Minister and high-level ministers of Downing Street to launch a Strategic Partnership Council between the United Kingdom and Saudi Arabia - an initiative to promote economic reforms in Saudi Arabia and promote cooperation on issues such as education, culture and security.
However, Prince Salman said Qatar would not be barred from attending an Arab summit hosted by Saudi Arabia later this month.
But as Britain rolled out the red carpet for his visit, many people were furious about the visit considering Saudia Arabia's role in the war in Yemen and the country's human rights record.
"This vindicates the engagement that we have with Saudi Arabia, to be able to sit down with them", she said. "It is great that the Saudi leadership has taken recently several decisions to enable Saudi women to take up more jobs in the local employment market and the ministry is extending continuous support to women, especially women with special needs to enter the job market", she added.
May defended herself when questioned by her political opponent, Labour leader Jeremy Corbyn, at the weekly "Prime Minister's Questions" session in parliament.
This will also go beyond current trade relations with British non-oil exports to Saudi Arabia totalling 6.2 billion pounds in 2016 and imports from Saudi Arabia totalling 2.6 billion pounds.
'Wahhabism, a strict interpretation of Islam, dominates life in Saudi Arabia, and all Saudis are considered Muslims, ' Open Doors said on its website.
Saudi Arabia is the main player in a coalition supporting the Yemeni government against the Houthis in a war which has caused a humanitarian catastrophe.
But May touted the relationship between Britain and Saudi Arabia, saying it's critical for anti-terrorism concerns. In the meantime, the crown prince has been given sweeping powers and has launched an ambitious program, Vision 2030, to modernize the country.
Welby also "voiced his distress" about the ongoing conflict in Yemen where is fuelled by Saudi-led airstrikes and has been described by the United Nations as "the world's worst humanitarian disaster for 50 years".
The three-day visit will include a second Royal audience - dinner with the Prince Charles and Prince William on Wednesday - and a prestigious visit to May's country residence on Thursday.
