Narrative:

While being vectored for 27L at egll we experienced wake turbulence events. Two of them were unable to be corrected for by the autopilot and had to be manually corrected. The second one exceeded 30 degrees in bank. Both of these events were a hard roll. I asked ATC what kind of aircraft we were following and they told us it was a 777-200. They then allowed us to slow to 150kts to increase the separation between us. We were advised that we had .2 miles from the minimum recommend separation at the time. There was zero wind at 4000 ft and the surface winds were calm.
