The British, US and French governments are risking a new ground war in Libya.
They have already sent troops to protect oil fields and pipelines and positioned troops in neighbouring countries.
They are preparing to send thousands to Libya itself.
British troops are now “training” Tunisian soldiers on the Libyan border. And British special forces have been deployed to join US military counterparts in Libya.
The Tunisian state has said it is talking to Germany and the US about using drones on its Libyan border.
The US has already used drone strikes against Isis in Libya. France is conducting military exercises with Egypt in the Aegean Sea, close to Libya’s eastern border.
The US is pressuring Italy to commit 5,000 troops to the operation.
Last month defence secretary Michael Fallon was asked in the Commons if he would guarantee MPs a debate “in advance of any decision to deploy UK Reaper aircraft outside Syria and Iraq”.
The defence secretary replied, “No.”
Isis has taken advantage of the chaos left after the Libyan civil war in 2011, which saw Nato forces tear apart the country.
