An enemy Italy keeps British battleship construction alive

What would Britain send to help France in the Mediterranean if Italy joined the Central Powers, and could Jellicoe resist the deployment?

Britain would send pre-dreadnoughts, continue battleship construction, retain the R class, and drop the large-light-cruiser diversion.

Pre-dreadnoughts would likely reinforce the French in the Mediterranean. Italy's entry as an enemy would make continued Royal Navy capital-ship construction unavoidable. Any thought of canceling the R class would disappear. Resources intended for large light cruisers would instead be redirected toward the battle fleet.
