Johnson is expected to use the trip to make a plea for Scots to reject narrow separatism, the tabloid’s online edition said.
Sturgeon said on Sunday that if the Scottish National Party wins the local elections scheduled for May, she will push for another independence referendum.
Johnson has said, however, that the 2014 referendum, when Scotland voted against independence by 55 percent to 45 percent, was “once-in-a-generation vote,” so London will not grant permission for another.
The Scottish leader argues that Brexit changed the whole scenario two years later because Scotland was forced to leave the European Union although a large majority of the Scottish voters had opted for remaining within the bloc.
