Just some quotes from online:
Gregory Campbell, the DUP MP for East Londonderry, concedes the negotiation is “more slow and more complicated than we thought”.
John Redwood: "I have often said that Brexit could be easy”
Liam Fox: [uk-eu] “one of the easiest [trade deals] in human history”
&
[We will have] 40 trade deals ready to sign “the second” after Brexit in March 2019.
David Davis:
May 2016: "The hard-headed, pragmatic businessmen on the continent will do everything to ensure that trade with Britain continues uninterrupted." (but)
Sept 2016: “It may be the most complicated negotiation of all time."
Farage: "We could do a deal with America in 48 hours"... ""The people of Norway (and) Switzerland ... are happy,...Those countries have their own deals, to maintain the type of trading relationship they want.""
Johnson: post-Brexit UK will “still have access to the single market”, plus “intense and intensifying” cooperation with Europe.
Gove The UK would still be able to trade freely within Europe even if it left the EU and was not part of the single market
Raab: “I hadn’t quite understood the full extent of this, but if you look at the UK and look at how we trade in goods, we are particularly reliant on the Dover-Calais crossing."
I dunno... it just seems like those campaigners sure didn't expect this much slog.
