Readers will have been following Guido’s series on those Tory and Labour MPs who have been enjoying the generous hospitality of the Saudi regime. However, keen Middle East observers may have noticed a conspicuous absence from Guido’s lists so far. Regular readers of the Saudi press or even the Daily Mail may recall that a certain Mr Keith Vaz also paid a visit to Saudi Arabia in December last year…

According to Arab News, Vaz visited the King Salman Humanitarian Aid and Relief Center in the Saudi capital Riyadh, meeting with its General Supervisor Dr Abdullah Al-Rabeeah and making a statement praising the organisation. Vaz even brought up his trip in Parliament and added that he had met with the Saudi Foreign Minister. Yet the only foreign trip that Vaz has declared in his register of financial interests is a trip funded by the Indian Government in January this year – despite Vaz being deemed “too unwell” to face a parliamentary investigation. There is no trace of Vaz’s Saudi trip whatsoever. Will the Standards Committee have to open another investigation into Vaz before they’ve even concluded the first?
