Brits Asked How Brainy or Stupid Public Figures Are

Sadiq Khan accused Trump of being "ignorant" on his views on Islam, Trump responded by challenging Khan to an IQ test.

​However, that's unlikely to happen, so Internet polling company YouGov asked more than 3,000 British people what they thought.

Coming out on top is current US President Barack Obama, followed closely by the late Conservative leader, Margaret Thatcher and Democrat Presidential candidate Hillary Clinton and former UK foreign secretary William Hague — rated as having above average levels of intelligence.

At the bottom sits former US President George W. Bush, marginally ahead of him is Donald Trump. Then UK Health Secretary Jeremy Hunt and leader of the UK Independence party, Nigel Farage, all rated as having below average intelligence levels.

​Sitting in the middle ranking positions with average levels of intelligence, according to the survey, is WikiLeaks founder Julian Assange, former UK work and pension's secretary Iain Duncan Smith, Scottish National Party leader Nicola Sturgeon and UK home secretary Theresa May.

To recap, Trump and George W. Bush are at the bottom, with a below average intelligence rating — and Obama and Thatcher are perceived to be the most intellectual public figures at the top, London Mayor Khan is in sixth place.

​So, if London Mayor Sadiq Khan did ever rise to Trump's IQ challenge, according to the British public it appears he would definitely win — if this survey and Trump's reputation is anything to go by.
