Kangaroos captain Darren Lockyer has denied taking drugs and says he was nowhere near retired Australian teammate Andrew Johns when he was caught with an ecstasy tablet in London last week.

The Broncos and Queensland State of Origin star said that he had been in the UK, but that he was not with Johns, who has since admitted to more than a decade of drug use.

"I think it's very unfair really, it's guilt by association," Lockyer told the Seven Network when asked about newspaper reports that he was with Johns.

"I was over there in London with my fiancee, working for the NRL.

"I was nowhere near The Church or anywhere like that," he said in reference to the nightclub where Johns said he'd been given an ecstasy tablet before being arrested by London police.

When asked if he took drugs, Lockyer said: "No. No."
