Giggs faced charges of causing actual bodily harm to his former girlfriend Kate Greville along with controlling and coercive behaviour. He also faced a charge of common assault of Greville's sister, Emma.
In a trial last year, the jury was discharged after failing to reach verdicts on the charges. Giggs denied all charges and a trial date of July 31st was set during a hearing at Manchester Crown Court.
However, Kate was no longer willing to give evidence in a retrial as the process had taken a toll on her and her sister, according to a BBC report.
"We have determined there is no longer sufficient evidence available to proceed in respect of the controlling or coercive behaviour charge and that it is no longer in the public interest to prosecute the remaining assault charges," a CPS spokesperson said.
Giggs made 963 appearances over 23 years for Manchester United, a club record, winning a haul of honours, including 13 Premier League titles and two Champions League trophies.
He represented Wales 64 times between 1991 and 2007 and took over as national coach in 2018.
He was replaced as Wales manager after initially stepping aside in late 2020 due to the case, with Rob Page taking over as national coach.
