I think for those of us who hope to travel overseas in May/June, we are most likely out of luck. The government has no interest in foreign travel at the moment, although, this is to a degree due to the fact that currently UK travellers are banned from a lot of countries as well.
We should wait and see what happens tonight. I personally think the UK government will not discuss foreign travel and this can be viewed as a good thing because that would mean things could change quickly.
If, however, staycations and travel within the UK are in the roadmap and as being allowed in June - as some papers are saying, we can forget any foreign travel before Sept/October.
