UPDATE 3-UK's Johnson delays lockdown easing by a month, citing Delta variant risk
* Last stage of roadmap out of lockdown delayed
* Extra time used to speed up vaccine program
* More infectious Delta variant cited for decision
* Without action hospitalisations could surge (Recasts with details of announcement)
LONDON, June 14 (Reuters) - Prime Minister Boris Johnson delayed his plans to lift COVID-19 lockdown restrictions by a month on Monday, warning that the more infectious Delta variant meant if he did nothing, hospital admissions could hit the peak of the first wave of the pandemic.
Under the final stage of a plan outlined by Johnson in February, he had hoped to lift most social restrictions on June 21, meaning pubs, restaurants, nightclubs and other hospitality venues could fully reopen.
That much-anticipated step was pushed back to July 19.
"I think it is sensible to wait just a little longer," Johnson told a news conference. "As things stand, and on the evidence that I can see right now. I'm confident that we will not need more than four weeks."
The extra time would be used to speed up Britain's vaccination program - already one of the world's furthest advanced - by shortening the recommended time between doses for those aged over 40 to eight weeks from 12 weeks.
The situation would be reviewed on June 28, which could allow the reopening being brought forward, although Johnson's spokesman said this was considered unlikely.
In recent weeks there has been fast growth in new cases caused by the Delta variant, first discovered in India. Health officials believe it is 60% more transmissible than the previous dominant strain and scientists have warned that it could trigger a third wave of infections.
On Monday, Britain recorded 7,742 new COVID-19 cases and 3 deaths. Johnson said Britain was seeing cases growing by about 64% per week and the number of people in hospital intensive care was rising.
