But in a defiant speech to the European parliament, Carney called for ‘deep cooperation’ and said polling showed the overwhelming majority of Canadians supported closer ties with Europe.

All four supporting acts for the upcoming dates of Ed Sheeran’s tour have withdrawn in solidarity with fellow opener Macklemore. The American rapper was removed from Sheeran’s tour after comments made onstage in support of Palestine. Sheeran responded that venue owners – including Robert Kraft who owns the New England Patriots and its home stadium – had objected to Macklemore’s appearance on the tour. But after he had tried to negotiate with the venue owners “at length to build bridges,” ultimately the promoters made the decision to pull the plug. Artists who have pulled out include Finneas, Aaron Rowe and Beoga. Lucy Hough speaks to Guardian assistant opinion editor Jason Okundaye – watch on YouTube.
