Boris Johnson calls for unity after the victory of the earth

British Prime Minister Boris Johnson urge people to “allow healing to start” after his huge conservative party won. The United Kingdom has been bitterly divided since voting to leave the European Union three years ago, and the result of the elections means that Britain’s exit from the European Union will happen in January. But this also means that Johnson will face great challenges in preserving the UK countries together. CBS News’ Ian Lee reports from London.
