It’s Wednesday morning here in London, thanks for joining us and welcome to our live coverage of the coronavirus crisis.
Here are some of the latest developments from the UK and around the world:
- It’s a big day for parents and children in England, as schools open their doors to all pupils for the first time in almost six months. Schools will look different, with one way systems, screens keeping pupils apart and staggered start times
- A group representing the UK families of people who've died with coronavirus accuses British Prime Minister Boris Johnson of being "heartless" after he said he would not meet them. Last week Mr Johnson had suggested he would be willing to talk to group members
- In Scotland hundreds of thousands of people in Glasgow and surrounding areas are now living under coronavirus restrictions after a rise in cases over two days. People won't be able to meet other households indoors, but shops, cafes and pubs remain open
- Meanwhile, lockdown restrictions affecting more than a million people in parts of Greater Manchester, Lancashire and West Yorkshire have been eased – despite strong opposition. Councils say ministers are causing chaos and confusion by lifting them too soon
- Australia's economy has plunged into its first recession in nearly 30 years as it suffers the economic fall-out from the coronavirus. It’s gross domestic product (GDP) shrunk 7% in the April-to-June quarter compared to the previous three months

Millions of pupils in England return after historic shutdownMillions of pupils in England are returning to school today after almost six months away.
Schools are expected to look different, with one-way systems, screens keeping pupils apart and staggered start times.
Many pupils will be given inductions so they understand the new rules, such as staying in their "bubble" groups and where to use social distancing. Teachers will be assessing what and how much their pupils need to catch up.
Ministers are urging parents to send their children back but it's unclear how many will do so, although attendance is compulsory in England.
Some recent polls suggest families are keen to see children back in class but others have not been so positive.
In Scotland, where pupils returned several weeks ago, official statistics show one in 10 pupils is absent. Pupils in Northern Ireland have already returned, and those in Wales are returning later this week.

How parents can help their children settleSean Coughlan - BBC News, education correspondent
Our education correspondent has been gathering advice for all those anxious parents and children with first-day nerves.
Leading educational psychologist, Daniel O'Hare, says there's a real need to recognise the physical, mental and emotional impact of going back.
Children are likely to be "drained" by the sudden "overload" of being in school after being cocooned at home for so long, says Dr O'Hare. "It will be very new to go back into that full-on setting with 30 children in a class."
Dr O'Hare says parents can help reduce anxiety by letting children know what changes to expect - how they will be in separate "bubbles", the one-way systems, the transport arrangements, the changes to timetables and the hand washing.
Another educational psychologist, Will Shield, based at the University of Exeter, says children should be told that it's "absolutely OK to be concerned" about going back and to talk about any particular worries.

Australia faces first recession in 30 yearsAustralia has technically lost its famous nickname as "The Lucky Country" and fallen into recession for the first time in almost three decades, the BBC's Australia correspondent Shaimaa Khalil reports.
GDP figures from the Australian Bureau of Statistics have shown that the economy shrank by 7% in the last three months as a result of the coronavirus pandemic.
For young people who have recently joined the workforce, this is something they've never experienced before. Australia has had a steady economy growth for decades with strong coal, iron ore and natural gas exports to a surging China. Tourism has also been a big driver of growth.
But this year, the country was hit hard - twice.
When the bushfires ravaged through more than 12 million hectares, tourism was bashed and thousands of small business lost months of essential seasonal revenue.
Then the coronavirus became a global pandemic. Australia closed down its borders and imposed strict social distancing rules. Nearly 1 million people lost their jobs as a result.

US won't join WHO-led vaccine effortsThe Trump administration has indicated that it will not participate in international coalition efforts to find and distribute a vaccine for Covid-19 because the World Health Organization (WHO) is involved.
The Washington Post newspaper reported that the White House would not join 172 other countries participating in a WHO-led initiative to "ensure equitable access to safe and effective vaccines, once they are licensed and approved".
White House spokesman Judd Deere said in a statement that the US would "continue to engage our international partners to ensure we defeat the virus, but we will not be constrained by multilateral organisations influenced by the corrupt World Health Organization and China".
US President Donald Trump has attacked the WHO over its handling of the coronavirus outbreak , accusing it of being biased towards China in how it issued its guidance.
Johnson 'heartless' for not meeting bereaved familiesCampaigners representing families whose loved ones have died from coronavirus are accusing Prime Minister Boris Johnson of being "heartless" in declining to meet them.
Covid-19 Bereaved Families for Justice says it wrote to the prime minister five times to request a meeting.
Asked by reporters about the letters, Johnson said he would "of course" meet anyone bereaved by Covid-19, but days later he wrote to the group to say he was "unable" to.
The group, which says it represents 1,600 families, said it was "devastated" to receive the letter, which it has made public .
Jo Goodman, co-founder of the group, said: "The prime minister has done a 360 - dodging five letters, then agreeing on live TV to meet with us, and now quietly telling us he's too busy. It's heartless."
