That politician is, of course, Jeremy Corbyn.
Theresa May is too busy selling the arms that end up in the hands of al-Qaeda and IS. Why would they want to kill her?
There have been three attempts on the lives of specific Members of Parliament since 11th September 2001.
One has been by an Islamist.
Another, the only one that has succeeded, has been by a Far Rightist of exactly the vintage to have known several members of the then and current Cabinets intimately in the 1980s.
And the third, which received by far the least coverage, has been by a fanatical Zionist.
All three of those have cause to target Corbyn. But none of them has any cause to target May. Quite the reverse, in fact.
