Selangor Umno Youth vowed to confront the Bersih roadshow tomorrow if its convoy crosses into Selangor.
Umno Youth exco member Armand Azha Abu Hanifah said that Bersih would be disrespectful if it goes on with its activities in the state tomorrow as it is the day Tengku Amir Shah Ibni Sultan Sharafuddin Idris Shah Alhaj will be crowned as the Raja Muda Selangor.
"When they cross (the border) and disrespect the proclamation of our prince, we will not hesitate to mobilise and stop these nonsensical groups from continuing with their activities in Selangor.
"Enough, Bersih! We will meet you at the three places you stated - Sabak Bernam, Sungai Besar and Tanjung Karang. We'll wait for you there," Armand told a press conference in Shah Alam today.
Armand also warned Bersih against "spreading hatred" among the people.
"Bersih, you take care of yourself... Stop spreading the politics of hatred among the people. Enough is enough.
"They said they will be in 200 locations, we will be wait for them in 2,000 locations to ensure they do not spread hatred among the people," Armand is quoted as saying by KiniTV.
Bersih is organising a series of roadshows to build momentum ahead of its Nov 19 rally to demand the resignation of Prime Minister Najib Abdul Razak over the 1MDB scandal.
Five Bersih convoys are expected to be flagged off tomorrow morning in Kedah, Perak, Johor, Sabah and Sarawak.
The Perak convoy will be flagged off in Teluk Intan and is expected to enter Sabak Bernam later in the day.
Last week, Bersih's convoys clashed with Umno and red shirt activists in Lumut and Teluk Intan.
Armand had also tried to confront the Bersih convoy in Johor but was stopped by police.
