International Cricket Council chief executive David Richardson says the "public has spoken" on cheating in the game and ball-tampering will not be tolerated.

Richardson addressed the ball-tampering scandal in the South Africa-Australia Test series earlier this year when delivering the MCC Spirit of Cricket Cowdrey Lecture at Lord's.

Australian captain Steve Smith and vice-captain David Warner were given 12-month bans from all international and domestic cricket for their part in the scandal, while batsman Cameron Bancroft was handed a nine-month suspension.

"Cricket's DNA is based on integrity, but we have seen too much behaviour of late that puts that in jeopardy and this has to stop," Richardson said.
