The five-horse race for the constituency of Aberdeen North, which takes in Old Aberdeen and the harbour, stretching from the River Don to the city centre.
Labour has only lost the seat twice since World War 1 including the most recent election which saw the SNP take the seat for the first time in its history.
The SNP landslide of 2015 saw Kirsty Blackman win the seat with 56.6% of the vote, giving her a majority of more than 13,000 against former Labour MSP Richard Baker.

Previous political experience: Councillor for Hilton, Stockethill and Woodside from 2007-2015. Worked for Brian Adam MSP before being elected to council and then part-time after being elected as councillor.
Non-political experience: Supporter of charity Woolly Hugs, worked in various Aberdeen bars, worked in the Bon Accord Centre selling pasta, worked as a carer. Some of these were while I was a councillor and some before I was elected.
Key issue: Household budgets. Salaries have not been rising but prices have. The generations coming through are set to be poorer than those that went before and I don’t think this is acceptable.
