Mottley made the announcement during an address to the Caribbean nation broadcast on her social media accounts.

The call comes just weeks after the Caribbean country became a republic and said goodbye to the British monarchy.

A former British colony that gained independence in 1966, Barbados in October elected Ms Sandra P. Mason as the country's first-ever president to replace Britain's Queen Elizabeth II as head of state. Ms Mason was sworn in as president on November 30, 2021.

Need for unity around common cause- Mottley

In a 37-minute, political address broadcast on her social media accounts, Ms Mottley listed her government's economic and financial achievements and said the economy was recovering despite damage to the tourism industry by the Covid-19 pandemic.

Arguing that the country was in the grip of a "silly season" as critics attacked her government's response to Covid-19, Ms Mottley said it was time to put aside partisan squabbling.

"I need for us to unite around a common cause, unite behind a single government, unite behind a single leader," she said, pledging to support whoever emerged victorious.

Nomination Day earmarked for Jan 3, 2022

Ms Mottley, the leader of the Barbados Labour Party and first female prime minister of her country, won election in May 2018 for a five-year term. The new ballot would be held on January 19, 2022, with nomination day earmarked for January 3, 2022, she said.

"We have, my friends, a country to build out, and we have a people to mould," she said. "Let us go on confident that if we can do so united as a people, there is no major challenge that can knock us down for the count fully."

In an apparent attempt to deflect potential criticism that she was moving opportunistically to consolidate power, Ms Mottley pointed to her party's overwhelming majority in Parliament and noted she still had much of her first term left to serve.

"Were I motivated solely by the need to survive," she said,"we could bask, my friends, in the glory of a 29-1 Parliament and ride Covid out for the next 18 months."
