Peru election: socialist Pedro Castillo claims victory ahead of official result

The son of peasant farmers says a new time has begun' as vote count gives him narrow lead against rightwing rival Keiko Fujimori

Peru's socialist candidate Pedro Castillo has claimed victory in the presidential election after clinging on to a narrow lead as the lengthy vote count ended, although his rightwing rival has pledged to fight the result and has yet to concede.

Castillo ended the count 44,058 votes ahead of Keiko Fujimori, who has made allegations of fraud with little proof and has tried to get some votes annulled. The result of the ballot held on 6 June has not been formally announced by electoral authorities, but Castillo hailed the win on Twitter.
