Critics in opposing parties and her own have accused her of stoking division and undermining the police.
British Prime Minister Rishi Sunak has described Saturday's planned march as disrespectful and said he would hold Rowley to account that the remembrance events are safeguarded.
Braverman, seen as a possible future Conservative party leader, often takes a harder line than her party as a whole on issues such as crime and immigration.
Opposition Labour Party leader Keir Starmer said Sunak was too weak to challenge her.
In a separate incident, two men were arrested over damage to the Cenotaph war memorial in the northern English town of Rochdale.
