Thousands of protesters in Thailand have handed their demands for reform to royal guard police after a planned march was blocked at security barriers in the capital, Bangkok.

One of the protest leaders, Panusaya Sithijirawattanakul, told reporters on Sunday that the police had said the letter would be sent to police headquarters.

The demonstrators’ demands include the removal of former junta leader Prayuth Chan-ocha as prime minister and a new constitution and elections, as well as reforms that would curb the powers of the monarchy.

They also called for a general strike and for Thai people to withdraw money and burn bank books of SCB Bank, which is linked to the royal family.
