The Welsh Government will propose to increase the number of Welsh speakers to one million by 2050 at the Eisteddfod in Abergavenny today.
The First Minister and Minister for Welsh Language will officially launch the proposal which is a result of the growing demand for Welsh-medium education.
The consultation also sets out to increase the number of people learning and able to use the language with their families, in their communities and workplace.
The Minister for Welsh Language says he's given the ambitious target of one million speakers to create a fully bilingual nation.
Alun Davies says he wants everyone to have the opportunity to learn through the medium of Welsh from early years through to higher education.
