KIEV, Ukraine — The daughter of jailed former Ukrainian Prime Minister Yulia Tymoshenko is asking prosecutors to investigate what she says is a denial of proper medical treatment to her mother.

Tymoshenko is serving a seven-year term on charges of abuse of office after a trial that the West has condemned as politically motivated.

Eugenia Tymoshenko on Friday urged the prosecutors to investigate charges that her mother is bedridden and in constant pain because prison authorities are denying her painkillers, misdiagnosing and mistreating her, a treatment the daughter says amounts to torture.

Authorities insist that Tymoshenko is being treated properly and she is set to be examined by a group of foreign doctors next week. Tymoshenko has accused President Viktor Yanukovych of orchestrating the charges to get rid of a political rival.
