DHAKA: UK prime minister David Cameron has promised Britain ‘will do what we can’ to help find more than 200 kidnapped Nigerian schoolgirls.

He made the comments as he held a sign bearing the ‘#Bring Back Our Girls’ slogan on the BBC's Andrew Marr show.

Cameron is the latest high-profile supporter of the social media campaign after US First Lady Michelle Obama was pictured with a similar poster.

The Islamist militant group Boko Haram has claimed the abductions.

During the programme, fellow guest Christine Amanpour, CNN’s chief international correspondent, handed Cameron the sign and asked if he would like to join the campaign.

Taking it from her, he replied, ‘Happily’.

Cameron later tweeted, ‘Proud to support #BringBackOurGirls’.
