Labour leader contender Jeremy Corbyn (R) shakes hands with London Mayor Boris Johnson as they arrive for a memorial service at St Paul's Cathedral in central London on July 7, 2015 in memory of the 52 victims of the 7/7 London attacks. Britain today marked 10 years since the London bombings with a minute's silence for the 52 victims, less than a fortnight after an attack in Tunisia highlighted the ongoing Islamist threat.
