Every NHS patient in England will be guaranteed access to GPs seven days a week if the Conservatives win next year's election, David Cameron says.
Boris Johnson vowed to "eat the 'Kippers for breakfast" as he sought to unite Tories and lambasted those who had defected to Ukip.
Mr Johnson hit back at "quitters and splitters" and told activists that victory in next year's general election was "within our grasp" as long as the party remained united.
To loud cheers the Mayor of London said:
Only the Conservative could deliver reform to the UK's relationship with the EU, he said. Comparing the successful fight against Scottish independence with the imminent by-election battles to retain the seats given up by defecting MPs Douglas Carswell and Mark Reckless, he said:
A former Thorpe Hall pupil has told ITV News the school's deputy headteacher "fooled us all", amid allegations he stored nearly 600 indecent images of children as young as nine.
Ex-maths teacher Martin Goldberg, 46, was found dead at his Essex home just a day after police had spoken to him about claims he bought images of naked teenage boys over the internet.
"He fooled us all. Pupils and staff. He was always friendly with pupils but then all teachers were," the ex-pupil said.
"Only sense of weirdness was just the usual - I thought he was bit lonely and sad and had no life outside of school.
"His life revolved around school. He was an OK teacher, very very involved with ski trips and extra-curricular stuff."
Essex Police says it currently has no evidence to suggest a former deputy headteacher - who stored hundreds of indecent images of pupils - made "inappropriate physical contact" with any child.
Theresa May says a new counter-terrorism bill tabled later this year would allow the prosecution of any British citizens who "participate in terrorist activities abroad".
She said the new powers, if signed into law, would enable police to seize suspects at the border, prevent their travel and have more time for investigations.
Nearly 600 images found on the computer of a deputy head of an Essex school are believed to be of boys aged from nine to 12.
Essex Police believe the images - which were reportedly taken from 2000 onwards - were taken on a camera hidden inside a bag belonging to Martin Goldberg.
Seventy-five images were taken in Thorpe Hall's male changing rooms, with 465 others taken in a local swimming pool and 38 from two other locations.

Theresa May has warned that Britain "must act to destroy" Islamic State.
Speaking to the Conservative Party conference, Home Secretary said if the extremist organisation was allowed to form a functioning state in the Middle East there would be a major threat to Britain, with the potential to use biological weapons against its enemies.
As ITV News Deputy Political Editor Chris Ship reports, May attacked the group who murdered British aid worker David Haines, saying: "They are not Islamic and they are not a state."
The headteacher of an Essex school where a former deputy head is alleged to have taken indecent images of pupils says everyone at the school feels "angry and betrayed" by the claims.
In a statement to ITV News, Andrew Hampton said Martin Goldberg - who was found dead nearly three weeks ago - had an "exemplary record" during his 23 years at Thorpe Hall School.
Friends of the Bristol teenager who is believed to be heading for Syria have been talking about their shock at her disappearance.
