Yoko steps back from Beatles business affairs, appoints Sean to play role

At age 87 in frail health, Yoko Ono has appointed her son, Sean Ono Lennon, to represent her business interest, including those related to the Beatles, The Daily Mail reports.

Yoko has been managing John's $800million fortune since his death in 1980.

Now Sean, 45, has been appointed a director at eight companies linked to the family and The Beatles according to The Mirror, including the multimedia Apple Corps.

Apple Corps had reported assets of $36million last year, and Sean is also believed to be taking over at Lensolo, managing John's solo material, Maclen, which publishes John's work in the US, and Subafilms, a music film company.
