Opening an opposition-led debate in a packed Commons chamber on 2 February 2011, shadow environment secretary Mary Creagh said the plans could result in the "sale of the century".
The claim was made by the SNP's Eilidh Whiteford, opening the debate in Westminster Hall, although the debate has previously taken place in the main chamber of the House of Commons.
In particular, members should be aware that they should be present for opening and closing speeches in debates in which they are contributing and that they should remain in the chamber for at least the two speeches following their contribution.
