According to procedures outlined in the constitution, the cabinet, which meets once a week on a Tuesday, will ask the president of parliament to invite the crown prince to become king.
Thailand's Crown Prince Maha Vajiralongkorn is set to become the country's next king after the Cabinet today formally recommended his name of parliament, paving the way for his endorsement after the death of revered King Bhumibol Adulyadej last month.
At the end of the meeting, all members of the parliament stood up and hailed together "long live the new king".
The crown prince still needs to accept the invitation in order for him to be formally proclaimed as the king.
Vajiralongkorn was originally supposed to assume the throne the day his father died, but in a surprise announcement, Prime Minister Prayuth Chan-ocha said the prince asked for the ascension to be put off so he had time to mourn.
Before his death, Bhumibol has endorsed his eldest son, Prince Maha Vajiralongkorn as his sucessor. "We expect an audience [with the prince] within the next one to two days", Prawit Wongsuwon, the defence minister of Thailand said.
"After this, we enter the parliamentary process".
A Thai lese-majeste, or royal insult, law criminalizes anything that is deemed to be an insult to the monarchy.
Until recently the crown prince spent a large amount of time in Germany, where he owns several properties.

That law makes the open discussion about the royal family's role all but impossible inside the kingdom.
But he has left behind a deeply polarized country, trapped in a cycle of political protests, coups by an arch-royalist military and entrenched inequality. Bhumibol's coronation was in 1950, four years after succeeding his brother King Ananda Mahidol, who died of gunshot wounds in unclear circumstances.
Thailand's current government is stacked with generals who staged the last coup in 2014.
Dubbed the "lost decade", Thailand's most recent period of political unrest coincided with Bhumibol's increasingly frail health and fewer public appearances.
Vajiralongkorn, a certified pilot, has yet to achieve his father's widespread adoration.
Rumours over his private life have also trailed him, gilded by three-high profile divorces and a recent police corruption scandal linked to the family of his previous wife.
Unlike his father, who was unexpectedly thrust into power at the age of 18 with the mysterious death of his brother in 1946, he was anointed as the Crown Prince in 1972.
Historically, the new monarch in Thailand is only crowned once the previous monarch is cremated.
