Martin Wolf 主张采用「瑞士方案」来代替重新加入，该方案由一系列条约组成，旨在使英国与欧盟单一市场和关税同盟保持一致。这种模式避免了公投，但需要接受劳动力的自由流动。从人口结构来看，英国需要持续的移民，但先前的移民诱因，例如欧盟东扩和欧元区危机，如今都已成为过去。
这种拼凑式的合作将巩固英国最至关重要的关系，因为在英国脱欧后，即使在 Donald Trump 卸任后，重返过去与美国的伙伴关系也是不太可能的。虽然短期内逆转是不可能的，但循序渐进的对齐提供了一条务实的前进道路。如果取得成功，这个框架可以在未来作为重新加入欧盟的更强大平台。
Discussing the UK's prospects of rejoining the EU, Martin Wolf notes that a full reversal of Brexit is unrealistic and unnecessary. Rejoining would trigger a divisive referendum and complex negotiations without previous opt-outs, exhausting parliamentary terms. Yet, the EU remains the UK's primary economic partner, with 45 per cent of UK trade in goods still conducted with the EU in 2025.
Instead of rejoining, Martin Wolf advocates for a "Swiss option" consisting of a patchwork of treaties to align the UK with the EU single market and customs union. This model avoids a referendum but requires accepting the free movement of labor. Demographically, the UK requires continued migration, but former migration triggers, such as the EU eastern enlargement and the Eurozone crisis, are now in the past.
This patchwork would strengthen the UK's most vital relationship, as a post-Brexit return to the old US partnership is unlikely, even after Donald Trump. While a short-term reversal is impossible, step-by-step alignment offers a practical path forward. If successful, this framework could serve as a stronger future platform for rejoining the EU.
