I sincerely hope the kicking the economy is already taking forces Britain to rethink this leaving home like a sulky teenager

But we have already legally left at the end of January, so our options are limited. We can, however, still choose whether to leave like a sulky teenager or to leave like a mature adult. For all his faults Boris is a pragmatist and I think would try to find a reasonable working arrangement. Raab is a true believer who will not be swayed whatever evidence might arise that leaving at the start of say Jan 2022 rather than Jan 2021 would be beneficial to the country.
