This must be the first time Mary Nightingale presents on a weekend

When Mary joined ITN in about 2001 she quite regularly presented weekend bulletins prior to moving on to the Evening News.

Wasn’t she hired originally to cover Kirsty Young on the Lunchtime News? She was definitely presenting at ITN at the very end of 2000, as there is a video of her presenting on one of the days between Xmas and New Year:

Obviously she very quickly moved to the Evening News as that’s where Kirsty’s job moved. Kirsty then came back around June/July (?) that year, but left quite quickly (October I think) to go back to C5. Mary then returned to the EN, sharing with Katie Derham originally before becoming permanent co-host.
