Newspaper headlines: Passport 'shambles' and Bake Off 'battle'
Holidaymakers queuing in a Spanish airport for passport control make the front page of the Daily Mail.
The paper calls new, tougher checks imposed by Brussels a "shambles" and claims British families - coming from outside the Schengen free movement zone - are suffering the most, with waits of up to four hours.
Airline executives - the Mail says - are blaming airports for not upgrading their computer systems or recruiting enough border officials.
Energy price hikes
Other papers lead with the decision by British Gas to raise prices.
"Shameless" is the headline for the Daily Mirror - which calls Centrica's chief executive "greedy" for announcing the increase, while admitting that wholesale prices are falling.
The Guardian warns the hike could prompt a fresh round of increases by the rest of the "big six" suppliers.
A government source tells the paper that the regulator Ofgem must act quickly to protect poorer customers, adding that ministers were still prepared to use legislation.
The Sun says a new BBC cookery programme - with Mary Berry as a judge - has sparked accusations of plagiarism.
A source at Channel 4 complains that similarities between Britain's Best Cook and the Great British Bake Off "have not gone unnoticed" and "will not be overlooked" once the programme goes to air.
The paper lists the similarities and differences. For example, Mary Berry will judge different dishes every week in a patriotic search for the country's best cook...but won't be with Paul Hollywood, in a tent.
The Guardian has seen list of more than a thousand vacant properties - and their owners - in the borough where the Grenfell Tower was destroyed by fire.
The proprietors include the former Mayor of New York Michael Bloomberg who owns a Grade II listed mansion, a Ukrainian oligarch and a luxury property developer.
The Times reports that efforts to conserve the population of hump-back whales in Australian waters may have had a savage, unintended consequence.
Fishermen and surfers have linked growing whale numbers to a recent spate in deadly great white shark attacks - and the government has ordered an inquiry into whether the two are related.
The president of a New South Wales surf group tells the paper he's in no doubt shark numbers are on the up - and that a cull should be a foregone conclusion.
'It was easy'
Finally, the Sun has spoken to the British man who sent hoax emails to high-profile figures in the White House - prompting several to respond, sometimes emphatically.
Posing as Reince Preibus - the ousted Chief of Staff - the unnamed prankster provoked former communications director, Anthony Scaramucci, into referencing Shakespeare and making a veiled threat.
"It was easy" he boasts. "Imagine if I had had sinister intentions."
