What are the chances that the new boundary commission lines for constituencies go into effect before the next general election in the UK?

Very unlikely. The next general election is not due until 2022, and the government is hardly likely to go for an early one, not after the mess it made of it last time. Theresa May has many qualities, but even her biggest fan would have to admit they do not include being a charismatic election campaigner.

If anyone else proposes it, that won't succeed, as a 2/3 majority is required to hold an early general election. Remember that Labour recently proposed a no-confidence motion and couldn't get a simple majority for that - it would have triggered an early election if it had been passed.

An Order in Council is not a Bill. It is an Order in Council, issued as a Statutory instrument under (in the case) the Parliamentary Constituencies Act 1986. The Act requires the draft Order to be put before both Houses, but as it is an Order in Council, Parliament does not have the final say - the Privy Council actually makes the Order, though that will be a rubber-stamp job.

The government is only struggling at the moment because the House of Commons is rejecting absolutely everything put before it about Brexit. It has rejected every deal that is on offer, it has rejected "no deal", so what DOES it want? We are being massively failed by our MPs of all parties. Not surprisingly the EU is also confused and quite reasonably its position is that it's not going to enter any more negotiations as there have been quite enough already. Meanwhile Labour's position, insofar as anyone can work out what it is, is to have Brexit in name only, which is a rejection of how the people voted and is actually worse than staying in the EU, as it would give the UK no say in Brussels over what the rules are.

At this point my personal view is that if MPs want to continue to behave like a bunch of squabbling toddlers, then so be it and it's about time they all had a good public spanking.
