News conference may be later than expectedpublished at 15:49 Greenwich Mean Time 15 January
We're hearing conflicting reports about the timing of the news conference in Doha.
Initially, reports from Qatar suggested it was imminent. We're now hearing the update could be held at 19:00 local time (16:00 GMT), or even later.
There are also reports it may be the Qatari prime minister's spokesman delivering the update, rather than the PM himself.
It's a fast-moving situation in Doha as months of negotiations come to a head - we'll have all the latest on this page.
