British terrorism expert Colonel Richard Kemp, whose job was once to monitor Saif’s movements for the British government in the early 2000s told the Daily Mirror: “He is highly likely to be the new leader as he is hugely respected amongst al-Qaeda but crucially he also respected amongst Islamic State.
“Not only could he be the new boss of al-Qaeda but he could also entice members of ISIS to join al-Qaeda or cause some kind of fusion between the two.
“There is co-operation between groups like this but Saif is so well-respected that he could cause even greater co-operation or even a merger.
“He’s an intelligent, strategic thinker and al-Qaeda has been in the doldrums under Zawahiri. All of this is about leadership and he could re-energise the movement.
“He could make al-Qaeda a much more effective organisation than it has been for a few years.
“The other thing to consider is his Iranian base, as Iran had facilitated al-Qaeda attacks before. That is hugely problematic for us.
“People don’t understand this – they say Iran could not support these groups because Iran is Shia and al-Qaeda is a Sunni group but simply is not true.
“Iran will support them. If they want America attacks they would rather al_Qaeda did it with their support so they do not get targeted. They have done it many times before.
“British intelligence has been aware of this man for many many years now and have been monitoring his movements and activities as far as possible.
“I was personally responsible when I worked in the Joint Intelligence Committee I was monitoring his activities at that time from 2002 – 2006.
“He was recognised then as being a very significant figure in al-Qaeda, in the top three or five.
“Now he is probably the top one now, with the demise of bin Laden and the potential demise of Zawahiri, his importance is even greater and more dangerous.
“Compared to Zawahiri he is likely to be a much more effective leader, at least so or more so even than bin Laden.”
