The British authorities say they were poisoned with a nerve agent administered by a pair of undercover Russian intelligence officers.
Russian Federation denies any involvement in the affair, which has deepened its worldwide isolation and led to a series of sanctions from the US and European Union countries.
Mr Putin's comments are the first time he has directly lashed out at Mr Skripal, who spent weeks hospitalised with his daughter.
"He was simply a spy".
Vladimir Putin labelled Russian ex-spy Sergei Skripal a "scumbag" and "a traitor to the motherland" today. "He's simply a scumbag, that's all", Putin added, in remarks that drew applause from parts of the audience.
"As for Skripal and so on, this is just the latest spy scandal to be inflated artificially".

Putin said that as a result of the deal, the market restored its balance of supply and demand, but the prices are still rising greatly due to "geopolitical issues", for which mainly the current USA administration is responsible.
Putin reiterated Russia's claim that it has nothing to do with the poisoning.
Asked about global sanctions on Russian Federation triggered by the March 4 poisoning, Putin denounced what he described as an "information campaign" over the case and said London has stonewalled Moscow's proposal to conduct a joint probe. "I sometimes look at what's happening around this case and I'm just surprised: Some guys showed up and started poisoning homeless people there in Great Britain".
"We didn't need to poison anyone over there".
"He was caught, punished and served a total of five years in prison".
The two Russian men Britain accuses of jetting to England to try to murder Skripal said in a TV interview last month that they were innocent tourists who had visited the city of Salisbury to see its cathedral.
