Where amphibious operations fit beside carrier strike

If the Royal Navy is organized around carrier strike, where does its amphibious mission fit?

Primarily in the Littoral Strike Groups, with room for additional arrangements.

A carrier-centered force structure still needs a place for amphibious warfare. Littoral Strike Groups are intended to carry that mission. A brief qualification that there may be more to the eventual structure leaves the final arrangement open. The fleet can therefore separate expeditionary force packages instead of putting every requirement into the carrier strike group.
