Like this wonderful example from Botswana :
President Ian Khama on Saturday 'ambushed' the Botswana Congress Party (BCP) in the heartland of Tswapong. In an unusual move, Khama turned up unannounced at a BCP rally at Borolong. Not only that: restraint was exercised by both sides when the BCP accorded Khama the opportunity to speak and Khama used the opportunity to show a touch of diplomacy.....One of the officials who had addressed the rally in Borolong was BCP Vice President, Dr Kesitegile Gobotswang, one of the fiercest critics of Khama's government. Gobotswang told Khama in Borolong that the BCP had nothing personal against him but that their concern was the manner in which Khama ran the government......Before closing their rally, BCP officials handed the microphone over to Khama to respond to some of the concerns raised. Whereupon Khama gladly obliged, but was careful not to stir any controversy.
