David Cameron posed with a banner reading #BringBackOurGirls while appearing on The Andrew Marr Show this morning, and said "we stand ready to do anything more that the Nigerians would want".
Mr Cameron added that a team was being sent to support the search for the more than 200 kidnapped schoolgirls but said "we can't just pile in and do whatever we'd like".
The Nigerian military has flown more than 300 sorties in the hunt for the abducted schoolgirls, a Major has told ITV News' Rageh Omaar.
A newly released video from Boko Haram reportedly shows the kidnapped Nigerian schoolgirls.
The man who started a viral hashtag campaign in support of the kidnapped Nigerian schoolgirls says it has forced the government to act.
