In his message, João Lourenço stated that he was certain that Daniel Chapo's victory "reflects the will and hope of the Mozambican people".
The President of the Republic also addressed in his message the "acts that sought to tarnish the exemplary process that resulted in the election" of Daniel Chapo and expressed his "expectation that the Mozambican authorities will firmly commit to punishing those responsible in an exemplary manner".
Finally, President João Lourenço stressed that he wanted to work together with Daniel Chapo "to increasingly strengthen the historic ties of friendship and cooperation that unite Angola and Mozambique, for the benefit of the progress and development of both nations".
The announcement on Thursday of the victory of the Frelimo candidate by the Mozambican National Electoral Commission reinforced the popular protests sparked days earlier by the candidate Venâncio Mondlane, supported by the Optimist Party for the Development of Mozambique (Podemos, an extra-parliamentary party), and which contested the alleged electoral fraud that resulted in Daniel Chapo's victory.
The Mozambican National Electoral Council (CNE) announced on Thursday the victory of Daniel Chapo (Frelimo) in the election for President of the Republic on 9 October, with 70.67 per cent of the votes, results that still need to be validated by the Constitutional Council.
Venâncio Mondlane, supported by Podemos, came in second place, with 20.32 per cent, totalling 1,412,517 votes.
In third place in the presidential election, according to the CNE announcement, was Ossufo Momade, president of the Mozambican National Resistance (Renamo), until now the largest opposition party, with 5.81 percent, followed by Lutero Simango, president of the Democratic Movement of Mozambique (MDM), with 3.21 percent.
Frelimo also won the legislative elections, strengthening its parliamentary majority, increasing from 184 to 195 deputies, and elected all provincial governors.
The announcement of the results made on Thursday by the CNE came on the first of two days of general strike and demonstrations across the country called by Mondlane against this year's electoral process, which have been marked by clashes between protesters and police on the main avenues of the Mozambican capital.
More than 300 people were arrested, according to the police, and on the streets and neighbourhoods of Maputo, the capital, the trail of clashes with protesters who took to the streets burning tyres and blocking avenues was visible on Friday morning, with a strong police response, with armoured vehicles, canine teams, tear gas and shots fired into the air.
