MailOnline has released footage showing Bolton responding with "No" when asked if he would be standing down as leader of Britain's eurosceptic party.

The Mail on Sunday published a series of messages sent by his girlfriend, Jo Marney, to a friend in which she made offensive comments about Markle and black people.
