LONDON (Reuters) - Scotland's first minister, Humza Yousaf, said on Thursday he had decided it was in his country's best interest to end a coalition agreement with the Green Party, a move he admitted might make governing more difficult.

"Therefore after careful consideration, I believe that going forward, it is in the best interest of the people of Scotland to pursue a different arrangement," he told a press conference.

"We will now step up our ambition but we will do so as a minority government. That will be tough. We will seek to work not just with the Scottish Greens but with MSPs (Members of the Scottish Parliament) from across the chamber."
