My point is that UK politicians are obsessed with tariffs and free trade agreements, while in reality those play a minor role (as EU tariffs are generally very low). What really matters to companies though are non-tariff-barriers (regulations etc). By deciding to leave the single market, the UK has erected huge non-tariff trade barriers with their biggest trading partner (the EU).
