Ireland may return into a full national lockdown for a six-week period amid an increase in the number of coronavirus cases, British media reported.

The news came ahead of a cabinet meeting on Monday to discuss the current measures in place. Initial speculation was that the country would be placed under Level 4 or Level 4 Plus due to government reluctance to impose the highest level of coronavirus restrictions; Level 5.

On Saturday, the National Public Health Emergency Team (NPHET) recommended that the country move to Level 5. Under this level, all indoor gatherings will be prohibited and bars and restaurants only able to operate takeaway services.

Level 5 is similar to the lockdown measures implemented in earlier this year; however, schools would remain open.

Earlier this month, the government rejected a similar proposal and instead imposed Level 3 restrictions countrywide.

Irish Prime Minister Micheál Martin had argued that a move to Level 5 will have "severe implications" and risk hundreds of thousands of jobs.

Under Level 3, there are stricter restrictions on gatherings and people are advised to work from home unless absolutely necessary. People should also remain in their county with the exception of those who must travel for essential purposes. Additionally, only professional or elite sporting activities are allowed and sporting matches will be played behind closed doors.

Under Level 4, Level 4 all non-essential businesses will be shut and visits to private homes and social gatherings will be banned.

Micheál Martin is expected to deliver a public address later on Monday regarding what level of coronavirus restrictions the country will be placed in.
