Bitter fight over $63 MILLION Powerball win among a Trio

Newsagency owners embroiled in a $63million Powerball court battle could be forced to shut their store as the 'heart and soul of our family' is almost hospitalised with a serious health condition.

Kevin and Tania Parkes, who own City News Kalgoorlie in regional Western Australia, were ecstatic when their 'pay off your mortgage' syndicate won half the $120million jackpot on February 24.

Each of the 250 participants walked away with $261,986, with the couple taking home double the amount because they bought into the syndicate separately.

But their joy turned to fury when a former government worker, known as Mr Ing, claimed he was part of the winning syndicate and entitled to a stake of the multi million-dollar prize pool - which the Parkes insist is not true.

They will fight Mr Ing for the cash in the Supreme Court on August 2.

As the crunch civil case looms, Mrs Parkes opened up on Saturday about her husband's battle as a leg amputee with high blood pressure.
