Minor changes were made by way of Government amendments to the MH Bill as it went through the Committee stage in the House of Lords (including, annoyingly, mucking up the numbering for all of the clauses from about half way through). The current version of the Bill can be found here, and the Explanatory Notes here. The Bill is very difficult to read in isolation, as it is a Bill amending the Mental Health Act 1983. I have therefore done an unofficial version of the MHA 1983 as it would look if amended by the Bill as it stands after the end of Committee stage in the House of Lords.
I have also done a walkthrough of the MHA 1983 as if it would look if amended by the Bill as introduced (nb, this was recorded prior to Committee stage in the House of Lords – only minor changes have been made subsequently).
