I'm still trying to figure out a good way to have a British Mozambique. I'm thinking the consitutional crisis in Portugal in the 1820s (I think it was then?) results in a smallscale revolution with some incredibly radical effects, such as the new leader, a dictator calling himself 'Emperor', blaming Britain for the sub-par status of Portugal and ending the ancient alliance.
As punishment, the British annex Mozambique and East Timor, as well as all of Portuguese India except Goa.
