  A future linear collider will complement the programme of the Large Hadron
Collider, especially for precision physics. The RADCOR community has an
important part to play in refining the predictions for rates and processes in
Electroweak, Higgs, SUSY, top and QCD physics, for e^+ e^-, e^- e^-, $\gamma
\gamma$ and $\gamma e$ collisions.
