The Danish Brexit act is a temporary scheme and will apply until replaced by a permanent solution. The Danish Brexit act applies to British citizens and their family members, who are legally residing in Denmark on the withdrawal date in accordance with EU-rules on free movement. This in itself will not affect many tourists who visit cities like copenage on their vacations and regularly use bus rental copenhagen
for their activities in Denmark. The law will also apply to frontier workers who work in Denmark on the withdrawal date while residing in another EU / EEA-country.
As the other countries see, they prepared for it. However, new UK Prime Minister Boris Johnson says he plans to renegotiate the Brexit deal agreed with the EU by his predecessor Theresa May. He says he is committed to leaving on 31 October come what may.
Mr Johnson's plan is to negotiate with the EU to remove the Northern Ireland backstop from the withdrawal agreement (WA). The backstop was designed to ensure there could be no return to a hard border on the island of Ireland. (It would keep the UK in a customs union with the EU if there is no free trade agreement that avoids a hard border ie physical infrastructure and checks on goods.)
