Netanyahu's office stressed that he has had limited inter-personal contact in recent weeks, conducting "most of his meetings via video conferencing from his residence."The news comes as Netanyahu, 70, is widely expected to agree on an emergency unity government with his election rival Benny Gantz to tackle the coronavirus pandemic. The two fought three bitter but inconclusive elections over the past year, with neither securing enough support to form a viable coalition government. Gantz was given the task of forming a government following March 2 elections but there was no guarantee he would succeed where he had previously failed, especially given rifts within the anti-Netanyahu bloc. Gantz, a centrist, was elected speaker of Israel's parliament last week and has committed to backing an emergency unity government with Netanyahu, citing the need to combat Covid-19.Negotiations on Sunday between Gantz and Netanyahu failed to yield a final agreement, with no fresh talks between the sides officially reported since.Netanyahu, in office since 2009, was in January charged with bribery, fraud and breach of trust, but the start of his trial has been delayed by the pandemic.He denies the charges.
