Tens of thousands of people in Japan have staged rallies, demanding the resignation of Prime Minister Shinzo Abe and his Cabinet - both embroiled in a cronyism scandal. Organizers say nearly 30-thousand people took part in Sunday's rally in front of the Diet. Abe's popularity has taken a battering after he was accused of selling government land at a heavily discounted price to a family friend. His Cabinet has also come under fire for trying to cover up that transaction. Abe has continued to deny involvement.
