Labour: We are working with Speaker to hold PM to account

Shadow Attorney General Emily Thornberry says opposition parties have "been in discussion" with the Speaker Lindsay Hoyle to devise a means of holding the prime minister to account for misleading Parliament if he refuses to resign. She accepts the "problem" they face is Boris Johnson's majority which means they can only force the PM's hand with the assistance of Tory MPs and urges members of the public represented by a Conservative to watch "very carefully" to see whether they "do the right thing". .
