The Chief Whip has been accused of "lying" to one of his own MPs after she was allegedly told to vote repeatedly during her maternity leave.

Julian Smith allegedly told Andrea Jenkyns that she had to vote in the wake of the snap election in June last year because Labour was refusing to "pair" with her.

Under the parliamentary convention pairs of MPs on different sides of the house agree not to vote so an absence for illness, travel or maternity leave does not affect the result.

Because she wasn't paired Ms Jenkyns returned to London from her Yorkshire constituency repeatedly to vote during her maternity leave.
