It's now 7-10am on Tuesday at Westminster - and their Lordships are continuing with their debate which began on Monday afternoon. Lord Toby Harris has updated his blog as the night has gone on - it's worth following - it can be accessed here.
The live debate can be followed on BBC Democracy Live, which unlike BBC Parliament can be accessed from outside the UK.
I have to say that watching the live feed, I've been very impressed by the numbers of Peers in the Chamber listening to the debate on the Opposition benches. As the Government has found out, their Lordships have a lot of stamina!
