The Spanish network for future colliders unites 16 institutes, among theoretical and high-energy physics institutes, technological centres, universities and representatives from Spanish science industry. The network is currently led by Alberto Ruiz-Jimeno (IFCA, UC/CSIC, Santander) and Marcel Vos (IFIC, UV/CSIC, Valencia).

The network has received the strategy with enthousiasm. It is very positive that the European high-energy-physics community has produced a clear document that outlines the future of the field. We are glad that the strategy update acknowledges the importance of a new electron-positron "Higgs factory" and hope that, with the supporting statement for the International Linear Collider, the project can now go ahead in Japan, with a strong contribution by Europe and CERN. It is good to see, furthermore, an ambitious program for the next large-scale facility in Europe, with the endorsement of technical studies into a very-high-energy hadron collider and a strong support for R&D into novel accelerating technologies and detectors, to advance theory and computing and to reinforce collaboration with industry.
