Voting boundaries across Oxfordshire have changed in the run-up to the General Election and here is an explainer of where you are eligible to cast that all-important ballot.

There are currently six electoral constituencies in the county but this number is set to soon become seven as Banbury in the north is split into a new Bicester and Woodstock voting area.

Below is a run-down of the changes you should be aware of for each constituency.

Oxford East 

Just over five per cent of the Oxford East constituency is being lost to the Oxford West and Abingdon constituency.

The area lost, designated by the percentage of residential premises moving to each successor, incorporates the bulk of the city centre which spans areas such as the High Street, St Giles' and Holywell.

Oxford West and Abingdon 

Oxford West will lose a chunk of its voters, 16.9 per cent of its residential premises, to the new Bicester & Woodstock constituency to the north as well as just under one per cent to Witney in the south east.

Notable areas lost in the north include Yarnton, Kidlington and Begbroke.

Banbury

The existing Banbury voter area has been split in two with almost 40 per cent of it going to the new Bicester and Woodstock constituency.

To offset this loss, Banbury has taken a chunk out of the Witney constituency which includes areas such as Chipping Norton and Charlbury.

Bicester & Woodstock

The new Bicester & Woodstock constituency includes what it says on the tin - Bicester and Woodstock.

A total of 38 per cent of the current Banbury constituency goes to Bicester & Woodstock with 51.8 per cent of the new constituency coming from Banbury.

Didcot & Wantage

The Didcot & Wantage constituency - previously known as just Wantage - has lost a part of its north-western voter base to Witney as well as a small percentage in the north to 2.6 per cent.

Areas lost to Witney include Faringdon, and Marcham which has been lost to Oxford West and Abingdon.

Henley & Thame

Henley is to have its area reduced and will be renamed Henley and Thame.

A total of 5.6 per cent has been lost to the new Bicester and Woodstock constituency which includes Bletchingdon and Kirtlington.

The 2.9 per cent lost to Didcot and Wantage includes Nuneham Courtenay and Culham.

Witney

The Witney constituency is losing a chunk of its north and eastern voters to Banbury and Bicester and Woodstock.

This has been offset by incorporation of new voters from the existing Wantage constituency.

Areas lost include Charlbury, Chipping Norton and Woodstock.
