I feel that Jo Swinson will need to rapidly gain some judgment if she is to succeed in leading her party.
She has stated that the Liberal Democrats will not join in any coalition with either of the other main parties. However, on the day that Boris Johnson was elected and forming his cabinet, Swinson "demanded" that Jeremy Corbyn and the Labour Party join her and the Liberal Democrats in laying down a motion of no confidence in the government.
Obviously, such a motion would have no chance of commanding a majority in the House of Commons (especially on that day), so Corbyn chose to ignore her demand.
So, perhaps talking to others in the future would get her further rather than making demands, and better judgment of when opportunities may arise may also benefit her party and her leadership.
