Queen and Adam Lambert have announced a new European tour date due to take place this summer.

They will play Poland's Rock in Wroclaw festival on July 7, which is held at the city's Municipal Stadium.

The news follows confirmation of two London shows Queen and Adam Lambert will perform together in July.

They were announced as a result of the cancellation of Knebworth's Sonisphere Festival, which incidentally was due to be held on July 7.

The Queen and Lambert juggernaut is also confirmed to play Moscow on June 30.
