The government has set out new emergency powers to tackle the spread of coronavirus with the publication of a bill.

Under the proposed legislation, airports could be shut and people held on public health grounds, while immigration officials could place people in isolation.

The powers would be time limited to two years under the proposals.

MPs plan to debate and vote through measures early next week.

Health Secretary Matt Hancock has said the powers were "proportionate to the threat we face".

The measures are expected to be fast-tracked through Parliament with the first debate on Monday - and MPs set to "nod them" through rather than proceeding through the voting lobbies as normal.

It comes as Northern Ireland announced its first virus-related death, and three more deaths were confirmed in Scotland.

Meanwhile, the government has promised to give more details on how school closures will affect students and parents after criticism over a lack of clarity.

The government plans to rush through its emergency legislation - all 329 pages of it - by Monday.

Some measures would, in happier times, appear draconian: the police could force people who are displaying symptoms of illness in to isolation.

Ports could be shut with little warning.

And regulations are being rapidly thrown aside to allow some medical students and retired clinicians to treat patients.

Protection for tenants from eviction will be added to the bill.

There is little political disagreement on the content but some unease at Westminster about the length of the emergency - the laws would last up to two years.

The government insists the measures could be "switched on and off" based on medical advice.

But some MPs are pressing for Parliament to have the power to review and renew the powers each month.

So to get the bill passed swiftly, the government may well be under pressure to cede the power to set "sunset clauses" to MPs - rather than leaving this to ministers at Westminster and in the devolved administrations.

Key measures intended to increase capacity in the NHS include:

Recently retired staff will be able to return to work without any negative impact on their entitlements

Special insurance cover will be provided for staff caring for staff outside their day-to-day duties

Paperwork will be reduced to help doctors discharge patients more quickly

Extra employment safeguards for volunteers to allow them to pause their main jobs for up to four weeks

Elsewhere, the process of arranging funerals could be fast-tracked as part of efforts to "manage the deceased in a dignified way" should the UK experience "excess deaths".

More court hearings could take place by phone or video while the Border Force could temporarily suspend operations at airports and other transport hubs if there are insufficient resources to maintain border security.

Most controversially, the bill gives unprecedented powers to law enforcement agencies to detain people and put them in appropriate isolation facilities if necessary.

It says it will help to "safeguard essential services" that could be at risk during the outbreak.

Ministers say they hope this will not be necessary as people will act responsibly, adding that the legislation will "support and protect the public to do the right thing and follow public health advice".

The bill also makes a provision for emergency volunteering leave - a new form of unpaid statutory leave - and compensation for any loss of earnings and expenses incurred by volunteers.

The government says this measure will enable relevant authorities, such as councils and health and social care bodies, to "maximise the pool of volunteers that they can draw on to fill capacity gaps" by addressing the risk to employment and loss of income.

MPs will be able to suggest changes to the bill, the Commons Speaker confirmed on Wednesday.

Speaking at Prime Minister's Questions, Labour leader Jeremy Corbyn said the opposition would hold the government to account to ensure the most "effective action" was taken to protect the public and NHS staff.
