Queen Elizabeth will set out on Thursday Prime Minister Boris Johnson's legislative agenda following his election victory, including a pledge to bring the EU Withdrawal Agreement bill back to parliament before Christmas, his office said on Saturday.

Johnson led his Conservative Party on Thursday to their biggest national election win since Margaret Thatcher's landslide victory of 1987, trouncing his socialist Labour Party opponent Jeremy Corbyn by winning 365 parliamentary seats and securing an overall majority of 80. Johnson fought the election on the slogan "Get Brexit done".
