Chile's student protest movement has claimed its second education minister as Felipe Bulnes stepped down and conservative President Sebastian Pinera named a replacement.
Chile's government has also confirmed that Agriculture Minister Jose Antonio Galilea is stepping down as well and will be replaced by National Agriculture Association chief Luis Mayol. Bulnes will be replaced by economist Harald Bayer.
Thursday's resignations come as a new poll shows that Pinera's approval rating has plunged to 23 percent, partly due to a long and bitter strike by students for reforms to Chile's education system. The rating was the lowest since democracy returned to Chile two decades ago.
The poll by the Center for Public Studies has a margin for error of 3 percentage points.
