A member of the House of Lords is among more than 400 people whose UK mobile phone numbers appear in a leaked list of numbers identified by NSO Groups client governments between 2017 and 2019, the Guardian reported. The Guardian said that the principal government responsible for selecting the UK numbers appears to be the United Arab Emirates, according to analysis of the data. The UAE is one of 40 countries that had access to the NSO spyware that is able to hack into and secretly take control of a mobile phone.

Dubai, the emirate city ruled by Sheikh Mohammed bin Rashid al-Maktoum, is also believed to have been an NSO client. The phones of Sheikh Mohammed's daughter Princess Latifa, who launched a failed bid to escape Dubai in 2018, and his ex-wife Princess Haya, who fled the country and came to the UK in 2019, both appear in the data. So too do the phones of several associates of both women – including, in the case of Haya, mostly UK-based numbers. As per The Guardian, those with UK numbers appearing on the list include: Lady Uddin, an independent member of the House of Lords, whose number appeared on the data in both 2017 and 2018.
