The latest coronavirus lockdown is another "significant challenge" facing the Wakefield district, the council's leader has said.
Prime Minister Boris Johnson announced the new lockdown last night, starting with immediate effect, meaning people must now stay at home except for a few permitted reasons.
Responding to the news, Wakefield Council's Labour leader Denise Jeffery said: "The government has made it clear the alarming severity of the situation nationally means we must all follow the new lockdown restrictions.
"Our district is already seeing an increase in infection rates and so it is absolutely crucial for everyone to take action now and prevent the infection rate increasing more rapidly."
If action isn't taken, NHS services will be "overwhelmed and more lives will be lost", Ms Jeffery added.
"This council will be here to support businesses and residents in any way we can," she said.
