MP condemns arrest of police officer in 'plebgate' row
Liberal Democrat MP John Hemming has condemned the arrest of a police officer in connection with the Andrew Mitchell 'plebgate' row.
The former chief whip resigned from his post after he was accused of calling police officers 'plebs' outside the gates of Downing Street.
He denies using the word.
It is claimed the police officer leaked false information about the incident to a national newspaper.
