As stated above, the Tories would be 3 line whipped and others in Labour/Lib Dems/Plaid Cymru/DUP etc would not oppose it or abstain.
If Tory MPs defied the whip and revolted it would have serious implications for the UK as we'd have not only an impotent opposition party, but an impotent party in power!
The Lords are getting pissy about it but the goverment has decided it is happening so it is.
Get over it.
Is it really that intense? Would I cope?
