Boris Johnson has dodged questions over whether he has used cocaine, despite previous admissions that he had taken the drug when he was at university.
The leadership frontrunner refused to answer questions on his conflicting statements over his use of the class A drug, when he launched his bid to be the next Tory prime minister.
Conservative leadership hopefuls are facing scrutiny over their consumption of illegal drugs after Michael Gove campaign was nearly derailed by the revelation that he had used cocaine more than 20 years ago, when he was working as a journalist.
Mr Johnson previously admitted using cocaine as a 19-year-old but then also claimed he had not actually snorted the drug in a separate interview.
Pressed directly on whether he had ever taken cocaine, Mr Johnson replied: “I think the canonical account of this event when I was 19 has appeared many times and I think what most people in this country really want us to focus on is what we can do for them and what our plans are for this great country of ours.”
Asked whether he had ever done anything illegal, Mr Johnson said: “I cannot swear that I have always observed a top speed limit of 70mph.”
