Hospitals in England could become “overwhelmed” with Covid cases if MPs do not back new restrictions, Cabinet Office minister Michael Gove has said.

Many Tory MPs oppose the tougher tier system, which begins on 2 December.

But writing in the Times, Mr Gove said MPs – who will vote on the measures next week – need to “take responsibility for difficult decisions”.

Labour is yet to decide whether it will support the new restrictions.

It has warned, however, that areas in tier three will be stretched to “breaking point” without further financial support from the Treasury.

When England’s four-week national lockdown ends on Wednesday, regions will be placed in one of three tiers: medium, high and very high.

In total, 99% of England will enter the highest two tiers, with tight restrictions on bars and restaurants and a ban on households mixing indoors. Only Cornwall, the Isle of Wight and Isles of Scilly will be in the lowest tier.

Some MPs say the new system imposes tight restrictions on numerous areas with low cases, and are calling instead for a more localised approach.

But Mr Gove has defended the new system, saying that, unless action to slow the spread of coronavirus is taken, the NHS could be “broken” and hospitals “physically overwhelmed”.
