Prime Minister Benjamin Netanyahu is poised to ask the Knesset for immunity this week, Channel 12 News reported on Saturday.
Netanyahu is currently facing charges of fraud, bribery, and breach of trust in three corruption cases.
Likud officials, however, said he has not yet made his final decision on the matter.

"Contrary to reports, immunity is only a temporary issue for a tenure period only and is not an evasion of prosecution," the Likud said in a statement.
"In any case, Prime Minister Netanyahu has not yet decided on the issue and will announce his decision in the coming days."
After winning the Likud leadership primary by a landslide last week, Netanyahu is expected to argue that the public has given him a vote of confidence, meaning he needs immunity to be able to run the government without needing to deal with a trial, Channel 12 reported.
But even if Likud wins the March 2020 elections, there is still the question of whether a prime minister under indictment can form a government. The High Court of Justice is expected to debate this issue later on Sunday.
