Newspaper headlines: 'Doomsday' and 'Thorpe's hitman' pictured

Neither the Sunday Telegraph nor the Observer will make pleasant reading for Theresa May this morning.

The Telegraph carries comments from the former Cabinet minister Priti Patel, who warns that the Conservatives are "abandoning their position as the party of meritocracy".

Ms Patel says the Tories have become "very, very lazy" in the battle of ideas against Labour.

She says she resents the "negativity" about Brexit emanating from the top of government and highlights Mrs May and Chancellor Phillip Hammond for criticism.

On its front page, the Observer prints an interview with a major Tory donor who calls for Michael Gove to replace Mrs May as prime minister.

Crispin Odey, a hedge fund manager, tells the paper he is concerned that Mrs May cannot "carry Brexit through".

But inside, the paper's chief political commentator Andrew Rawnsley says the woman once branded "a zombie prime minister" has, so far, proved "remarkably difficult to finish off".

"In the event of nuclear Armageddon," he writes, "I have a growing suspicion that cockroaches would find that they shared the post-apocalypse wasteland with Theresa May."

The Mail on Sunday claims to have found a key witness involved in what it calls "the greatest political cover-up of the 20th Century".

The paper says it has tracked down Andrew Newton - the man who allegedly tried to kill the gay ex-lover of the former Liberal leader Jeremy Thorpe. He had been assumed dead by police, says the paper, but is instead living under an alias in Surrey.

The Mail says Mr Newton could provide evidence that the full details of the assassination plan were covered up in the 1970s. Gwent Police say they are pursing "lines of enquiry".

Many of the papers remember the London Bridge terror attack - one year on.

A photograph on the front page of the Sunday Express shows one of its own journalists - who survived the attack - standing outside Borough Market.

The paper's city editor Geoff Ho tells how his life has changed for the better since the atrocity. He is now engaged to be married to a woman who was, at the time of the attack, just his friend.

"The terrorists didn't win," he says, "in fact they did the opposite... they brought us all closer together."

The Sunday Mirror says 12 Islamist terror plots have been thwarted in the UK since last year's attack.

The security services, it reports, are currently handling five hundred live operations, involving around 3,000 "subjects of interest".

The Sunday Times reveals government plans for what it calls the "doomsday, no-deal Brexit".

The paper says a document drawn up by senior civil servants predicts that Britain would be hit with shortages of medicine, fuel and food within a fortnight if the UK tried to leave the EU without a trade agreement.

One source tells the paper that the port of Dover would "collapse on day one".

In response to the report, a spokesman for the Department for Exiting the European Union has called the claims "completely false" adding: "A significant amount of work and decision making has gone into no-deal plans, especially regarding ports and we know that none of this would come to pass."

The Sunday People carries an interview with a boy of 13, who says he managed to lose £80,000 of his dad's money - by gambling online.

The paper says the teen stole his father's credit card and used it to place bets of up to £3,000 at a time.

In its editorial, the paper says it's "shocking" that 250,000 children in the UK have been identified as "problem gamblers" - and calls on the government to take action.
