You're probably right but my booked flights are on typical leisure routes so any decision will probably be taken for me when they all get cancelled.

Do you have a sense yet of what's likely to happen with mixed work+leisure trips? I've got a couple of work trips scheduled where I'm staying the weekend before/after to bring the cost down. Assuming the trips don't get cancelled, I'm wondering if I need to rebook them (and get work approval for the change fees and higher ticket prices...) to loose the weekend leisure bit, or if there being some work part to the trip might be good enough. May have to wait for Tuesday/Wednesday to know though!

Yes I would mainly be worried about which flights will actually take place whether if I can leave the country or not. If you are flying to ATH, ZRH, CDG, MUC, FRA, MAD, etc, more likely your flight will go ahead as there are more people with actual needs to travel.

I suspect there was more to this, as in the reason for the visit shifting or changing during the discussion. But as you say the birth mother would need to be vulnerable, or the child, it's quite tightly defined (essentially under watch from a local authority's social service department), so if the mother and baby were healthy then childcare vists were not (and are not in the Tier system) allowed.

I suspect that the test will be that if a Border Force officer asks you to prove (e.g. at the airport departure gate) that you have work related travel, that you can do so. I very much doubt there would any issue about the exact length of the trip. So I think it will be fine to stay longer than work needed, the point is to stop non essential travel, whereas work travel is now deemed essential. It's not about calibrating travel.

You can travel for that purpose if it is directly care related (e.g. his care home couldn't cope) or for end of life / terminal illness visits. That's already in the Tier system for Vulnerable Groups. You can also visit if there is a legal imperative (e.g. relating to wills, sorting out care contracts, quite a long list).

My BA flight out of the UK is scheduled for a few days after the beginning of the lockdown. Does anyone knows if hotels will kick out guests on the 5th? (the front desk agent said probably not but wasn’t sure)

I’m trying to figure out if it’s better to stay and fly as planned or pay a significant fare difference and fly on the 4th.

A number of hotels stayed open during the first lockdown, where only essential workers could stay in hotels. This time any worker is allowed to stay in a hotel. So if your hotel has business guests it should be OK, particularly if you live overseas. There will still be a stay-at-home objective on you.

A shame mental health isn't considered "essential" by this government.

I will make that judgement myself and to hell with the government and all its agents, come what may.

Have I seen correctly that people in Wales are banned not just from going to England but also from travel abroad, during the English lockdown?

What's your cunning plan?

I have a relative abroad currently in ICU. Things are looking stable but if things get worse/are looking really bad, is going to see a relative in ICU abroad allowed? I would only go if it is looking like, to be blunt, death is inevitable, so I can say goodbye. (I assume going for a funeral is fine.)

See my previous answer on this, leaving home in Wales without a reasonable excuse currently would be an offence. The purpose of the travel would be very relevant therefore, but it is safe to say going on holiday would not be seen as a reasonable excuse .

I was referring to the news reports today about what applies after their fire break.
