The shadow schools secretary has claimed that taxpayer's money is being given to radical Muslim group Hizb ut Tahrir.
It describes itself as "global Islamic political party working for the re-establishment Islamic caliphate" or state.
At prime minister's questions last week Conservative leader David Cameron claimed two schools in Slough and Haringey have been established by a "front organisation" for Hizb ut Tahrir.
Those schools had been given £113,000 of government money, "some of which came from the pathfinder scheme" designed to counter Muslim extremism.
Michael Gove raised the issue again at schools questions this afternoon.
He said that further investigation by the BBC had revealed that the head teacher of the Slough school has previously described western culture as "dangerous" and democracy as a "corrupt tradition".
Junior minister Ian Wright replied that Gove should put his concerns in writing and they would be investigated.
The government said it would ban Hizb ut Tahrir after the 7/7 bombings in London in 2005, but did not do so.
Cameron told the House last week that he asked two years ago why it had not been banned, and said the radical group regards non-Muslims as targets on the battlefield.
