Newspaper headlines: May's premiership and 'children damaged by cannabis'

The Sun calls on Theresa May to say she will resign, if such a move will persuade MPs to approve her Brexit deal in a third Commons vote this week.

Under the headline "Time's up Theresa", the paper says it is making the suggestion with regret, having supported Mrs May since before she was prime minister.

It argues that the agreement has such a slim chance of getting through, the prime minister cannot risk it being rejected again.

Boris Johnson launches his latest attack on the government's approach to Brexit in the Daily Telegraph.

The former foreign secretary's views are spelled out in a series of headlines, superimposed onto a photo of him driving away from Chequers yesterday, that takes up half the front page.

"We have blinked. We have baulked. We have bottled it completely. It is time for the PM to channel the spirit of Moses in Exodus, and say to the pharaoh in Brussels: Let my people go."

In its opinion column, the Daily Mail quotes that famous line from Oscar Wilde's poem, The Ballad of Reading Gaol: "each man kills the thing he loves".

It goes on to suggest that "Tory Eurosceptics might do well to note these words", advising them to throw their weight behind Mrs May's deal, or risk losing Brexit entirely.

The Financial Times, meanwhile, alleges that data handling at a major call centre operated by British Airways has been insecure for several years.

The FT says it has been told by both current and former staff that the centre, at Bremen in northern Germany, is vulnerable, in part because it has an "archaic" IT system.

British Airways tells the paper: "We continue to invest heavily in data security. All our systems and procedures at our call centres in Bremen and elsewhere are regularly audited."

'Dementia supplements'

Google comes under fire in The Times, because it sold adverts for pills that claim to promote normal brain function.

The paper said the adverts came up if people entered search terms such as "Alzheimer's pills", and "dementia supplements".

The Alzheimer's Society is quoted saying that "it's incredibly concerning if people looking for information on dementia drugs are not receiving the right support or treatment".

Google tells the paper that adverts for products which offer miracle cures are a violation of its policies and are therefore removed.

Finally, the i welcomes the decision to award the singer Suzi Quatro a "rock 'n' roll icon" award.

According to the paper, Quatro - who had number one hits in the 1970s, including Can The Can and Devil Gate Drive - has inspired stars including Courtney Love, Chrissie Hynde and KT Tunstall.

The headline is: "Award at last for unsung queen of female rockers".
