Some politicians want the assembly to get more powers

The party is publishing its written evidence to the Richard Commission, which was set up to examine the issue a year ago.

But it has declined to comment on the future of the assembly.

Prime Minister Tony Blair has gone on record saying he does not want more constitutional change, but others in the party are believed to wish for an increase in the assembly's powers.

In its submission to the commission, Welsh Labour will not make any recommendations either way .

Instead, party bosses in Wales will now wait for the commission to make its own conclusions, before responding to them.

Lord Richard of Ammanford is heading the inquiry

Opposition parties have accused Labour of ducking the issue.

The Richard Commission is examining the assembly's work since its inception in 1999.

It has been taking evidence from a wide range of sources, including political parties and the general public.

It will recommend on issues including the electoral system and whether the body needs greater authority, such as those held by the law-making powers of the Scottish Parliament.

However, any advised changes to the devolution settlement would only be made at Parliament in Westminster.
