Brazil's public sector finances improved further in November, central bank figures showed on Monday, as the deficit as a share of the overall economy shrank to its smallest in over a year and the national debt fell for the third straight month.

The primary deficit for the consolidated public sector, before interest payments are factored in, fell to 1.24% of gross domestic product in the 12 months to November from 1.25% the month before, the smallest shortfall in 13 months.
