We were cleared to push and had new weights uplink three times. We called to cancel push clearance and Captain told tug driver to stand by while they loaded the FMC. Once ready they called for push clearance and I heard the Captain tell the tug driver brakes released cleared to push. The aircraft started moving with no response from tug driver. The Captain tried to contact the tug driver but there was still no response. We moved back about ten feet before coming to a stop. One of the push crew got on headset and told us there was no one on the tug.
The 777 crew were cleared to push back; released the brakes and moved back about ten feet before realizing that there was no one driving the tug.
