The UK's new polar research ship is to be named RRS Sir David Attenborough, although Boaty McBoatface topped a public vote.

The £200m vessel will be named after the world-renowned naturalist and broadcaster, Science Minister Jo Johnson has confirmed.

The move, coming days before Sir David turns 90, will recognise his "legacy in British broadcasting", he said.

Sir David said he was "truly honoured" by the decision.

He said that he hoped "everyone who suggested a name will feel just as inspired to follow the ship's progress as it explores our polar regions".

"I have been privileged to explore the world's deepest oceans alongside amazing teams of researchers, and with this new polar research ship they will be able to go further and discover more than ever before."

And while the ship will not be named Boaty McBoatface, one of the remotely operated sub-sea vehicles will be named Boaty in recognition of the vote.
