Tens of thousands of people have protested in Tel Aviv against what they say is corruption within the government and the slow pace of investigations against Prime Minister Benjamin Netanyahu.

Netanyahu is suspected of receiving luxury gifts from wealthy supporters and has also faced police questioning over a secret deal he allegedly sought for favourable coverage with the publisher of top-selling Israeli daily Yediot Aharonot.

Protesters late Saturday massed in a large boulevard of an upmarket neighbourhood in the Israeli city, an AFP reporter said, shouting "Shame" and "Bibi go home", referring to the prime minister by his nickname.

The rally -- dubbed "the march of shame" -- was organised by the leaders of weekly protests which have taken place outside the home of Attorney General Avishai Mandelblit over the past few months.
