Downing Street representatives said it was “still too early” to determine whether the Indian variant could delay lifting all coronavirus restrictions on June 21.
They also stated that there had “not been any significant changes” in the past 24 hours.
The Prime Minister’s official spokesman said: “At the moment we are keeping a very close eye on the data.
“There is still, similar to yesterday, not been any significant changes that currently suggest we need to change our course of action.
“We are monitoring that very carefully but it is still too early to make a definitive judgment.
“We will monitor the data, crucially both on hospitalisation rates in these outbreak areas and the ongoing work on the transmissibility – both that work is ongoing, so we will aim to update next week.”
