British embassy in Egypt reopens to public
The building in Cairo suspended services on 7 December and told members of the public not to visit the site.
But the Foreign Office said the issues had been resolved and Foreign Secretary Philip Hammond confirmed all services had resumed on Tuesday.
He thanked the Egyptian government for their "close co-operation".
During the closure, visa applications among other services were suspended.
'Open for business'
John Casson, Britain's ambassador to Egypt, said: "It is great news that, thanks to the vital cooperation of the Egyptian government, we have today restarted full public services at the British embassy in Cairo.
