The protesters - the so called Red Shirts - are loyal to a former prime minister, Thaksin Shinawatra, who has been urging demonstrators to overthrow the government.
The telecoms billionaire, who was ousted in a military coup in 2006, fled Thailand in August before being sentenced to two years in prison on corruption charges.
He has made a series of speeches by telephone and video in recent weeks encouraging his anti-government forces to take to the streets. Jakrapob Penkair is a leading member of the red shirt protest movement, and he spoke to Karen Percy yesterday evening in Bangkok.
Presenter: Karen Percy, South East Asia correspondent
Speaker: Jakrapob Penkair, deputy secretary to former Prime Minister Thaksin Shinawatra and president of the Democratic Alliance Against Dictatorship
