Amanda Knox will jet home from Italy to the US via London just as the prosecution are planning to launch an appeal against her acquittal for murder.

A source told The Daily Telegraph in Perugia that chief prosecutor Giuliano Mignini wants to pursue the case which, if successful, could overturn the acquittal and reinstate the convictions against her.

After 11 hours of jury deliberations, Amanda Knox and ex boyfriend Raffaele Sollecito were cleared of killing 21 year old British student Meredith Kercher in 2007

The decision followed an independent review of the forensic evidence.??

Amanda Knox flies home, cleared of murdering Meredith Kercher

Amanda Knox "sunny and sweet" Sollecito tells court

Knox, who has spent four years of a 26 year sentence in prison, broke down in tears when the verdict was read out last night.

Knox’s family reacted with jubilation at the verdict but Meredith Kercher’s father John described the ruling as “ludicrous” and said it made a “mockery” of the original trial.

Speaking from the family home in Surrey, Kercher told the Daily Mirror: "It is ludicrous. How can they ignore all the other evidence?"

“I thought the judge might play it safe and uphold the conviction but reduce the sentence. But this result is crazy.”

“We are all shocked, we could understand them reducing the sentence but completely freeing them, wow."

Meredith Kercher was found dead with her throat cut in the Perugia house she shared with Knox in 2007.

Rudy Guede, also convicted of the murder in a separate trial, remains in jail

Guede claims that Knox and Sollecito were involved.
