Ronan Farrow supports his sister's allegations against their father

Woody Allen's son Ronan Farrow has attacked his own publisher over its plans to publish his father's memoir.

The journalist, whose Catch and Kill was published by Hachette, said he was "disappointed" to learn that the firm will release Allen's autobiography.

Farrow's sister Dylan, who claims she was molested by Allen in 1992 when she was seven, called Hachette's decision "deeply upsetting" and a "betrayal".

Hachette has defended its decision to publish Allen's Apropos of Nothing.

"We do not allow anyone's publishing program to interfere with anyone else's," said Michael Pietsch, the US publisher's CEO.

Allen has always denied molesting Dylan Farrow, saying she was coached to make the claim by his estranged former partner, the actress Mia Farrow.

The film-maker was investigated over the abuse allegations at the time of the incident but was never charged.
