The Polish government says it has backed a plan to lower the retirement age to 60 for women and 65 for men, from the current level of 67 for all.

Lowering the retirement age was among key promises that the Law and Justice party and the party's candidate for president, Andrzej Duda, made during their successful electoral campaigns last year.

The Cabinet of Prime Minister Beata Szydlo backed Duda's proposal on Tuesday. Parliament's approval is still needed for it to become law, however.

The proposal reverses the previous government's decision to increase the retirement age to 67 for all, arguing it was needed to adapt to an aging society.

Government spokesman Rafal Bochenek said the new law could take effect Oct.1, 2017.
