The Conservative party gained both Scunthorpe and Great Grimsby at this year’s General Election.
Both seats were Labour strongholds for decades, with the latter being by the party for 74 years.
Now, the constituency’s are held by two female Tory MPs.
But, who are the newly elected Conservative representatives in northern Lincolnshire?
Holly Mumby-Croft, Scunthorpe
Holly Mumby-Croft currently sits on North Lincolnshire Council as a Tory councillor in Broughton.
She chairs the Health Scrutiny Panel for North Lincolnshire and last year oversaw the meeting which saw Thames Ambulance Service stripped of its non-emergency patient transport contract.
As well as sitting on the local authority, she has been a member of Broughton Town Council since 2010 and, according to Conservative Home, has campaigned against wind farm developments in the past.
Mrs Mumby-Croft, who also stood for MP unsuccessfully in 2017, put the steel industry and Brexit at the centre of her campaign this year.
She defeated Labour candidate Nic Dakin, who held the seat since 2010, by 6,451 votes.
Lia Nici, Great Grimsby
Lia Nici has spent most of her life in Grimsby and lives in Laceby with her son and husband.
She spent 20 years a college lecturer was also a former executive producer of local television channel Estuary TV, which closed down last August.
Mrs Nici spent many years on Laceby Parish Council before she stepped down in April last year over a dispute on how to use a £70,000 grant for solar energy.
She was elected as a Conservative councillor for Scartho ward to North East Lincolnshire Council at last year’s local elections.
Now, she has been elected as MP for Great Grimsby after defeating Labour candidate Melanie Onn with a majority of 7,331.
The constituency was a Labour stronghold for 74 years.
In her victory speech, she said it was “an honour” to represent the town and that it had “amazing potential”.
