The Israeli parliament on Monday advanced a bill that would make it harder to oust Prime Minister Benjamin Netanyahu over the corruption charges against him, as it plowed ahead with a broader plan to overhaul the country's legal system in defiance of mass protests. Lawmakers in the Knesset gave preliminary approval during a late-night vote on the bill, which would allow the parliament to declare a prime minister unfit to rule only for physical or mental reasons. The body was expected to vote later on a measure that would allow the Knesset to overrule Supreme Court rulings and enact laws that had been struck down. Both bills require additional votes before being enshrined into law.
