LATEST: Sir Paul McCartney has hit back at his estranged wife Heather Mills' accusations of violence and excessive substance abuse during their marriage, insisting he will "vigorously" defend his innocence. Mills filed court papers yesterday (18OCT06) alleging the former beatle had attacked her when she was pregnant and on another occasion stabbed her in the arm with a broken wine glass. MCCartney was also said to have verbally abused his wife, calling her an "ungrateful bitch", and objected vociferously when the amputee asked to purchase an antique bedpan so she didn't have to crawl to the toilet during the night. Among a series of alleged incidents pinpointed in the court papers, MCCartney is said to have become "very angry, yelled at her, grabbed her neck and started choking her" in August 2003 when she asked him if he had been smoking cannabis. In April 2006, MCCartney is accused of pouring a bottle of red wine over his wife's head before throwing the wine in his glass at her. He "then reached to grab the respondent's (Mills) wine glass and broke the bowl of the glass from the stem. However, MCCartney has broken his silence in order to defend himself against the shocking claims. A statement released by the star's lawyers reads: "Since the breakdown of his marriage Sir Paul MCCartney has maintained his silence in not commenting on the media stories believing that it was best for all concerned, particularly his children, for there to be some dignity in what is a private matter. "Our client would very much like to respond in public and in detail to the allegations made recently against him by his wife and published in the press, but he recognises, on advice, that the only correct forum for his response to the allegations made against him is in the current divorce proceedings. "Our client will be defending these allegations vigorously and appropriately." A close pal of MCCartney, Geoff Baker, speaks more plainly to British newspaper The Sun, "I would not believe her if she told me the sun set in the west, and I mean that. "I would not believe this fabricating t**t. She wants her name in the paper and is only saying it for attention." The couple, who have a two-year-old daughter, BEATRICE, separated acrimoniously earlier this year (06).
