London: Britain's Olympic and world champion Mo Farah said the British media were trying to destroy his achievements and repeated that he was a clean athlete during an emotional outburst on Sunday.

"It's like I have achieved what I have achieved and you are trying to destroy it," he told reporters. "You guys, so many times towards me, you have been unfair. "

Farah won silver in Saturday's 5,000 metres at the World Athletics Championships - his final track race of a career in which he won two successive Olympic 10,000 and 5,000 gold medal doubles.

In February, Farah's coach Alberto Salazar denied administering banned supplements to his athletes and issued a firm rebuttal of what he said were false allegations against him in a British newspaper.

Farah has repeatedly denied wrongdoing. "It's like a broken record repeating myself," said Farah. "If I have crossed the line, and Mo Farah has done something wrong, then prove it."

"You can write what you like but I'm a clean athlete... and I sleep well at night, loving my kids, hugging my kids, showing (them) what's right. That's all that counts.

"History doesn't lie - everybody's proud of me," he said. "I'm going to still keep fighting, keep working, making my country proud," said Farah. (Reuters)
