Answer by taking a quote from the following article:

Michael Philip Jagger was born into a middle-class family in Dartford, Kent. His father, Basil Fanshawe "Joe" Jagger (13 April 1913 - 11 November 2006), and grandfather, David Ernest Jagger, were both teachers. His mother, Eva Ensley Mary (nee Scutts; 6 April 1913 - 18 May 2000), born in Sydney, Australia, of English descent, was a hairdresser and an active member of the Conservative Party. Jagger's younger brother, Chris (born 19 December 1947), is also a musician.

Jagger's relationship with bandmate Keith Richards is frequently described as "love/hate" by the media. Richards himself said in a 1998 interview: "I think of our differences as a family squabble. If I shout and scream at him, it's because no one else has the guts to do it or else they're paid not to do it. At the same time I'd hope Mick realises that I'm a friend who is just trying to bring him into line and do what needs to be done."  The Rolling Stones album Dirty Work (UK No. 4; US No. 4) was released in March 1986 to mixed reviews, despite the presence of the US top five hit "Harlem Shuffle". With relations between Richards and Jagger at a low, Jagger refused to tour to promote the album, and instead undertook his own solo tour, which included Rolling Stones songs. Richards has referred to this period in his relations with Jagger as "World War III". As a result of the animosity within the band at this time, they almost broke up. Jagger's solo records, She's the Boss (UK No. 6; US No. 13) (1985) and Primitive Cool (UK No. 26; US No. 41) (1987), met with moderate success, and in 1988, with the Rolling Stones mostly inactive, Richards released his first solo album, Talk Is Cheap (UK No. 37; US No. 24). It was well-received by fans and critics, going gold in the US. The following year 5x5: The Continuing Adventures of the Rolling Stones, a documentary spanning the career of the band was released for their 25th anniversary.  Richards' autobiography, Life, was released on 26 October 2010. According to a 15 October 2010 article published by the Associated Press, Richards described Jagger as "unbearable" within the book, noting that their relationship has been strained "for decades". By 2015, Richards' opinion had softened, while still calling Jagger a "snob" (providing supporting evidence from Jagger's daughter Georgia Mae), he adds "I still love him dearly ... your friends don't have to be perfect."

did the tour still go as planned without him?
instead undertook his own solo tour, which included Rolling Stones songs.
