Why is Netanyahu accusing Palestinian Israeli parties of fraud?

Prime Minister claims the parties accepted foreign funding.

The votes have been counted in Israel’s general election and there is no overall majority.

Benjamin Netanyahu has accused Palestinian Israeli parties of “stealing” the polls and accepting funding from Qatar to do it.

Those parties have denied wrongdoing, the Electoral Commission has found no evidence of fraud and Qatar denies any involvement.

So, is this a way for Netanyahu to stop Palestinian Israeli parties from forming a coalition with the opposition to unseat his Likud party?
