image captionThe Daily Telegraph leads with calls for richer countries to give more coronavirus vaccines to poorer nations - or risk new variants emerging that could bring about future lockdowns. In an article for the paper, the heads of the World Health Organization, International Monetary Fund, World Bank Group and World Trade Organization warn the current situation risks creating a "two-track" pandemic.
image caption"Third wave alert" is the headline for the Metro, which says there are fears the final stage of easing lockdown in England due on 21 June may be delayed. The paper says scientists are warning a rise in cases of the variant first identified in India could become a surge and overwhelm hospitals. A less gloomy warning features on the other half of the front page, with the headline "heat wave alert", alongside a picture of two children enjoying a lido near Bristol on Monday - the hottest day of the year so far.
image captionMeanwhile, the Guardian says scientists are urging the government to speed up administering second doses of Covid vaccines and to delay the decision on easing lockdown on 21 June amid concern about the spread of the Indian variant. The variant is believed to be more transmissible than the one previously dominant in the UK and somewhat more resistant to vaccines, particularly after only one dose, the paper reports.
image captionThe Sun is urging its readers "to join a race against time to maximise Covid jabs" and sign up as vaccine stewards to help beat the Indian variant. Like other papers, it also warns the variant could threaten plans to ease restrictions on 21 June.
image captionThe Daily Mail uses its front page to launch a campaign to end what it describes as "rip off" tests for holidaymakers. MPs, travel chiefs and consumer groups have accused the government of reneging on its promise to significantly drive down the price of travel testing, the paper reports.
image captionThe Daily Express hails a "sunny outlook" for the economy, with vaccines boosting the UK's recovery. Economists have upgraded their forecast and now expect the UK to beat all major rich nations this year, with 7.2% growth, the paper reports. Alongside its lead story, the Express has a picture of a woman sunbathing on an inflatable on what it describes as a "record baker" of a day, with temperatures reaching 25C.
image captionThe Daily Star also focuses on the warm weather, urging readers to slap on the suncream after the UK recorded its hottest day of they year so far. The paper has a picture of a packed beach in Bournemouth, where sunseekers flocked to enjoy the bank holiday.
image captionThe school day in England will be extended by half an hour under a £15bn Covid rescue plan to help children catch up after the disruption of the pandemic, the Times reports.

image captionThe i reports that police are failing to tackle racism by officers - citing data revealing that out of 7,837 complaints to forces across the UK about racist behaviour only 181 resulted in formal action. Just 30 officers were sacked or resigned over a five-year period, according to figures from a Freedom of Information request.
image captionThe Daily Mirror leads with a story about a five-month-old baby who has been given "a chance of life" by a £1.8m drug on the NHS. Arthur has received gene therapy Zolgensma for a spinal disorder which had reduced his life expectancy to just two years, the paper reports.
image captionThe Financial Times leads with a story about accountancy group EY, which the paper reports is to centralise power in a new European executive team. It says the move has raised concerns among some partners that any financial hit related to Wirecard - the payments group which EY audited until it collapsed in a fraud scandal last year - might also be shared.
