Prime Minister David Cameron says Liverpool striker Luis Suarez set "the most appalling example" by biting Chelsea defender Branislav Ivanovic.
While speaking on BBC Radio 5 Live, Mr. Cameron said: "As a dad and as a human being, do I think we should have tough penalties when football players behave like this? Yes."
However, Cameron, who made previous comments about the incident before the FA panel made its decision earlier this week, denied that he had deliberately intervened.
"I made my own views clear, just as a dad watching the game," Mr Cameron added.
"I have a seven-year-old son who loves football, loves watching football and when players behave like this, it sets the most appalling example to young people in our country."
Liverpool boss Brendan Rodgers has claimed that the previous comments from Mr Cameron swayed the panel's decision.
Suarez has apologised to 29-year-old Serbia defender Ivanovic and was fined by Liverpool on Monday. He has also accepted the 10-match ban given to him by the FA.
