Arlene Foster's new pro-Union project suffered a setback as former Scottish Conservatives leader Ruth Davidson rejected claims she would join the ex-DUP leader on tour.
Dame Arlene at the weekend announced her new group, the Together UK Foundation, saying it would be aimed at making "the positive, rational case" for maintaining the United Kingdom.
Writing in the Sunday Telegraph, she said it would involve "mainstream pro-Union voices from across the entire country to highlight the benefits that the Union brings to us all".
