Protests have erupted in central London against the re-election of Britain’s Conservative prime minister David Cameron, with demonstrators throwing bottles, cans and smoke bombs at riot police.

Scuffles broke out when the demonstrators, blaring hooters, banging pots and chanting obscenities, confronted lines of police outside the gate leading to the prime minister’s Downing Street residence. At one point a bicycle was hurled at police.

Police arrested five people, and four police officers and one member of police staff were injured policing this protest, a Scotland Yard spokesman said.
