Bob Diamond has said "This behaviour was reprehensible and it was wrong. I stand for a lot of people at Barclays who are angry about it."
The outgoing CEO of Barclays bank also questioned whether other banks were showing their real cost of borrowing during the 2008 crisis.
Mr Diamond said due to the focus on his leadership he decided it would be better to step down.
He denied that the UK's Financial Services Authority had told him trust had broken down between him and the regulators.
Mr Diamond said "I love Barclays." He was speaking at Parliamentary hearing into the Libor fixing scandal in London.
He said Barclays suffered because it was the first bank identified in the scandal.
He said in the 2008 crisis there were other banks which had secret loans and were struggling but they were able to borrow money at a lower rate than Barclays. He said "That did not seem right to us."
