David Cameron has drawn up a secret hit-list of Isis fighters who can be taken out at a moment's notice if the opportunity arises, it has emerged.
The National Security Council, which is chaired by the Prime Minister and meets weekly, authorised a list of about 10 jihadists earlier in the summer and included the two British Isis fighters who were killed by the RAF in a drone attack in Syria last month.
It means the RAF can launch another drone attack on anyone on the hit list without having to go back to the NSC or the Attorney General for approval.

Among them is Mohammed Emwazi, otherwise known as Jihadi John, who has been filmed carrying out barbaric murders on a number of British hostages.
Last month's secret killing of Cardiff-born Reyaad Khan and Ruhul Amin, from Aberdeen, was revealed by the Prime Minister yesterday. It was the first time the UK government targeted a British citizen in a foreign country.

News of the hit list led to a father of two young British men who are believed to be fighting for Isis in Syria voicing concerns that they too are on the Government's hit list.
Ahmed Muthana, whose eldest son Nasser went to the same school in Cardiff as Mr Khan, said: “I am frightened because my sons are out there too. “I worry that they could be on a hit list. I don’t think I will ever see my sons again.”
The Prime Minister defended the killing of Mr Khan and Mr Amin, insisting it was "entirely lawful" and the Government was "exercising Britain's inherent right in self defence".

And Michael Fallon, the Defence Secretary, this morning said the Government would "not hesitate" to launch more secret drone strikes on targets in Syria in a bid to prevent potential terror attacks on the UK.
Mr Cameron told MPs that Mr Khan and Mr Amin had been linked to a number of plots in the UK, including ones to target public commemorations, understood to have been the VE Day and Armed Forces Day events this summer, which were attended by the Queen.
The security services had identified Mr Khan and a second UK-born target, Junaid Hussain, as "a direct threat to the UK", with evidence showing he was actively recruiting people to carry out terrorist attacks in the West.

In a statement in the House of Commons, the Prime Minister said: "Both Junaid Hussain and Reyaad Khan, were British nationals based in Syria who were involved in actively recruiting ISIL sympathisers and seeking to orchestrate specific and barbaric attacks against the West, including directing a number of planned terrorist attacks right here in Britain, such as plots to attack high profile public commemorations, including those taking place this summer.
"We should be under no illusion. Their intention was the murder of British citizens. So on this occasion we ourselves took action."
However Mr Cameron is coming under pressure to explain the legal basis for the drone attack, with MPs calling on him to disclose what evidence led him to authorising the first RAF killing of British nationals in a foreign country.
