Former PN MP and the current Law Commissioner Franco Debono launched a scathing attack on Prime Minister Joseph Muscat on Saturday, calling him the "most corrupt politician" that Malta has ever seen.

The criminal lawyer wrote on his blog on Saturday that "the time had come" for him to speak out and had an ominous warning for the Prime Minister, saying that: "tomorrow we would be able to speak better".

"You swallowed it hook line and sinker, because you were always a fool," the blog post read.

Since the publication of the blog post, Debono's website went down for a period of time although it now seems to be functioning, a turn of events that led the firebrand lawyer to allege on his social media account that Muscat and those close to him were leading the Maltese secret service and that this was the reason as to why they had not been investigated.

Saturday's post comes hot on the heels of another controversial post, wherein Debono said that from all the facts in the public domain one can argue that given the circumstantial evidence, the secret company Egrant belongs to Joseph Muscat or someone close to him.

"Muscat should stop playing hide and seek. I've known him since Form 2C and I've never known him to be particularly brilliant... The Egrant inquiry didn't find who Egrant belongs to nor did it find who it doesn't belong to, because it seems as though it excluded no one," he wrote.

He also wrote another blog post later to thank those who were encouraging him to stand as a candidate for the upcoming MEP elections, saying that he was listening.

Debono served as an MP for the Nationalist Party between 2008 and 2013, a term that will be remembered for his incessant attacks against his own party's Cabinet led by Lawrence Gonzi. It was Debono who eventually voted against a Budget Measures Implementation Bill in Parliament to topple the PN government. After the 2013 election, he was elected Law Commissioner by the Labour government.

Debono in a separate Facebook post on the Constitutional Convention also took aim at the President of Malta. 

He said the constitutional convention never took off because President Marie-Louise Coleiro Preca insisted and put pressure so that she would be the one to hold it.

He said that while he never had the problem of having theconvention fall under the patrimony of the President, he says:  "however it seems that her intention, and she even applied pressure for this, was for her to organise the convention herself."
