Equal marriage reforms will allow gay schoolchildren to "stand a little bit taller", David Cameron said as he heralded the 2013 Pride in London parade.
The Prime Minister told how he hopes youngsters would be able to see that Parliament "believes their love is the same as anyone else's love" as thousands of people prepare to descend on the capital today for the annual gathering.
Organisers expect the parade and festival to be the biggest lesbian, gay, bisexual and transgender event in London over the last decade.
