'Boaty McBoatface' research ship officially named after Sir David Attenborough

The UK’s new polar research shop has been officially named after broadcaster Sir David Attenborough.

The Duchess of Cambridge smashed a bottle of Champagne against the ship at a ceremony in Birkenhead.

An online poll had suggested the ship be named ‘Boaty McBoatface’ – but one of its robotic submarines has been given this moniker instead.
