Mr Johnson won the Tory leadership race just last week but his party has already begun polling at 29.8 percent rating in four different opinion polls. This marks a 5.5 percent increase in polls conducted before he took office. The only other Prime Minister who has managed such a huge feat is Tony Blair, according to data from Pollsters.

Mr Blair took the Labour Party up 11.8 percent in 1997 after his landslide election victory, from 47 percent to 58.8 percent. None of Mr Johnson’s Tory predecessors have managed his 5.5 percent boost for the Conservatives. This includes Theresa May, who managed a 3.5 percent increase, as well as David Cameron at 2 percent. John Major added a meagre 0.5 percent boost, while Margaret Thatcher actually went down by 3 percent.
