A judging panel that included Flag Institute representation has selected four finalists in the competition to select a flag for Northamptonshire.
Voting will now take place to choose the winning flag, as well as the preferred date for a Northamptonshire Day.
The poll will be open until 21 April and the winning design will be unveiled in May.
Cllr Joan Kirkbride, Chairman of Northamptonshire County Council commented:
‘Over the past two years here in the UK we have had ample opportunities to get out there and wave flags. Whether it has been to celebrate the Royal Wedding, the Queen’s Diamond Jubilee or supporting our Olympic heroes.
The Parliamentary Flags and Heraldry Committee is now encouraging communities across the country to get involved and register their own flags. We think this is a golden opportunity for Northamptonshire to find a flag we can be proud of.
We are looking for a flag which can help raise recognition of Northamptonshire across the country, express pride in our local community and celebrate the heritage and culture of our corner of the country.’
