Boko Haram militants stormed the school in Chibok in north-east Nigeria in 2014, taking the girls. It prompted the hashtag #BringBackOurGirls campaign movement.
Of the 270 girls kidnapped at least 195 remain captive. Nigerian president Muhammadu Bahari along with the country's army have made gains against Boko Haram, which terrorises parts of northern Nigeria, since 2014.
The Muslim president today reiterated his commitment to rescuing the remaining kidnapped girls, saying: "the Federal Government is willing to bend over backwards to secure the release of the remaining Chibok girls."
The British government has also restated its desire to eradicate Islamist terrorism in Nigeria.
In a joint statement Foreign Office Minister Tobias Ellwood and International Development Minister James Wharton said: "We are working side by side with Nigeria in the fight against Boko Haram and call for the release of all those who have been taken.
"During our visits to Nigeria last year, we heard how people's lives have been devastated by Boko Haram.
"We are committed to supporting Nigeria in the fight against these barbaric terrorists."
