Mohammed Sajid Khan from Bradford is believed to have been in the early stages of building an improvised explosive device to target Jewish communities in Manchester.
Between March and July 2011, he and his wife began to access online bomb-making manuals and bought products which could be used to build an explosive device.
His plot, planned with his wife Shasta Khan, was discovered by officers from the North West Counter Terrorism Unit.
They are due to be sentenced at Manchester Crown Court tomorrow. Mohammed Sajid Khan pleaded guilty to engaging in conduct in preparation for acts of terrorism at an earlier hearing.
