The commissioner would act on behalf of older people

The move will be discussed later by assembly members who are deciding which bills they want introduced in Westminster.

More powers over education and the suspension of the right-to-buy scheme for council homes in some areas will also be discussed.

But opposition parties say the debating process is a waste of time.

Wales already has its own children's commissioner, Peter Clarke, who is independent of the government.

The post was created after a report by Sir Ronald Waterhouse in 2000 about the abuse of children over a period of 20 years in children's homes across north Wales.

Alternative bills

The assembly cannot make its own primary legislation but instead asks the UK Parliament to pass laws on its behalf.

The assembly government said the proposals it wants to put forward are practical and will work with the current constitutional set-up.

Among the bills which could be introduced in the forthcoming session are plans for a commissioner for older people, a move to suspend the right-to-buy scheme for council homes in some areas and a scheme to extend powers over education.

Both Plaid Cymru and the Liberal Democrats have suggested alternative bills that would create a parliament for Wales.

Away from the chamber, the Conservatives have drawn up their wish list of bills, including one that would remove the first minister's power to veto senior civil service appointments.
