An estimated half a million Romanians took to the streets in another night of protests, with many calling on the government to quit even after it scrapped the corruption legislation that sparked a week of public outrage.

The prime minister, Sorin Grindeanu, stood firm, however, saying his government, which has been in office for barely a month, “has a responsibility to the people who voted for us” and would not resign.

The last six nights of noisy protests thronging cities and towns around the country have been the biggest outpouring of public anger since the toppling of communist dictator Nicolae Ceausescu in 1989.
