PRESS ASSOCIATION -- Prime Minister David Cameron will fly home early from Africa to concentrate on the escalating crisis in London over phone hacking and police links with the media.
Mr Cameron decided on Monday night to cut short his visit to Nigeria by around seven hours, returning on Tuesday afternoon rather than overnight, to give himself time to prepare to face MPs on Wednesday.
His return comes at the end of a trip, billed as a high-profile trade mission, which has been completely overshadowed by the hacking scandal and by the resignation of two senior officers at Scotland Yard.
During a stopover in South Africa on Monday, Mr Cameron faced repeated questions about his employment of former News of the World editor Andy Coulson, after Metropolitan Police Commissioner Sir Paul Stephenson and his assistant commissioner John Yates both quit over their links with Coulson's former deputy Neil Wallis.
The PM will make a statement on the affair to the House of Commons on Wednesday after announcing that he was extending the parliamentary session by a day to allow him to address MPs.
His announcement followed jibes from Labour leader Ed Miliband that the Prime Minister had left the country with the intention of staying away until MPs had quit Westminster for their summer break.
Mr Cameron had already trimmed what was originally intended to be a five-day tour of four African countries ending on Friday.
He dropped Rwanda and South Sudan from his itinerary in order to be able to return to London to deal with the aftermath of Tuesday's appearance before the Commons Culture Committee of media tycoon Rupert Murdoch, his son James and former News International chief executive Rebekah Brooks.
After flying into Nigeria from South Africa, Mr Cameron will use a speech in the capital Lagos to urge Africans to use aid, trade and political reform to make the coming years "Africa's moment".
Mr Cameron will say that the conditions are falling into place to transform Africa, lifting millions of people out of poverty and ending dependence on aid. And he will warn that, unless Britain and its businesses take advantage of this moment, they risk "missing out on one of the greatest economic opportunities on the planet".
