The prime minister said this on Thursday during his visit to the NLV Pharos lighthouse tender, which moored on the river Thames in London.
“(I was talking yesterday) about building a bridge from Stranraer in Scotland to Larne in Northern Ireland – that would be very good. It would only cost about 15 billion pounds,” Johnson said in a video published by Sky News.
While still serving as foreign secretary, the official proposed the idea and asked the government for the project’s estimates, and even called for building another bridge over the English Channel to link the United Kingdom and France.
“There is so much more we can do, and what grieves me about the current approach to Brexit is that we are just in danger of not believing in ourselves, not believing in Britain,” Johnson said, as quoted by Sky News.
The construction of such a bridge is seen as a potential solution to the Irish backstop, a measure that entails keeping the entire United Kingdom in the EU Customs Union, with Northern Ireland complying with some EU Single Market rules, in case of a no-deal scenario.
The UK voted to leave the European Union in 2016, but the withdrawal was delayed several times.
