"The supporters of this so-called boycott are a bunch of corduroy-jacketed lefty academics," Johnson stated, in an interview with Channel 4 news. 

"I cannot think of anything more foolish than to say that you want to have any kind of divestment or sanctions or whatever or boycott, against a country that when all is said and done is the only democracy in the region, the only place that has in my view a pluralist open society," he added, noting the boycotters are a "very small minority" who have "no standing in the matter." 

Johnson is on an official visit to Israel Monday, in a bid to strengthen economic ties between London and Tel Aviv - particularly in the business and high-tech sectors.
