Tax Credits (Income Thresholds and Determination of Rates) (Amendment) Regulations 2015

I have worked in many roles, and I have listened to the noble Lord giving advice. I know that after this debate many members of the public will ask what an earth was going on in the House of Lords. Could the noble Lord answer the question: if the House of Lords today amended or voted down this statutory instrument, could the Government in the Commons bring back a one-word-change statutory instrument within the next few days? Secondly, would he care to comment on the following? I listened very respectfully to the noble and learned Lord, Lord Mackay, who used an expression that I could not understand. Could the noble Lord explain why the noble and learned Lord thought that it would be offensive for the Government just to choose to bring this item forward in primary legislation? I did not understand the reasoning, but I am sure the noble Lord does.
