Mr Hague, who led the Tories from 1997 to 2001, wrote in The Daily Telegraph that Mr Johnson along with two other “decision-makers” will determine the outcome of a Brexit deal. The decision-makers mentioned alongside Mr Johnson included leader of the DUP, Arlene Foster and the Irish Taoiseach, Leo Varadkar.
Mr Hague said: “One, of course, is Boris Johnson himself.
“The second is Arlene Foster, leader of the DUP, whose support is needed to pass a deal through the current Parliament.
“The third is the Irish Taoiseach, Leo Varadkar.”
However, Mr Hague also indicated that the imposition of “customs checks” in Ireland may force the Irish Prime Minister to agree to consent to a new Brexit deal.
Mr Hague added: “No deal brings for Dublin the very outcome they have striven to avoid all along – the imposition of customs checks on the island of Ireland.
“It would be in their interests, if the “consent” issue were resolved in their favour, to summon the political will to work with London on how to make a customs arrangement work.”
Away from his vision of Ireland’s strategy, Mr Hague warned that the three parties could still take former Prime Minister Theresa May’s deal and add a time limit on the Irish backstop.
He admitted that if this was implemented then it would involve “a major climbdown” by all three players.
