Harrow’s Parliamentary constituencies will be drastically transformed by a proposed redrawing of electoral boundaries, with Labour set to suffer heavy losses in the borough as strongholds are cut adrift.

Three new seats – Harrow and Stanmore, Kenton, and Wembley and Harrow on the Hill, – will be created if the existing Harrow East and Harrow West constituencies are altered as suggested in the Boundary Commission’s initial proposals.

As part of the overhaul, a Ruislip, Northwood, and Pinner constituency will be created, as well as a Kenton constituency consisting of Barnhill, Belmont, Edgware, Fryent, Kenton, Kenton East, Kenton West, and Queensbury wards.

In Harrow West, Labour’s Gareth Thomas has been representing his constituents in Parliament since 1997, winning a majority of 2,208 over the Conservatives at the 2015 general election.

However the creation of a combined Harrow and Stanmore constituency would see Mr Thomas’ existing wards of Harrow on the Hill, Rayners Lane, Roxbourne, and Roxeth all trimmed from his constituency.

Particularly worrying for Mr Thomas is the fact that two of these wards were Labour strongholds at the last set of local elections.

Of the five wards put forward for inclusion in the same new constituency – Canons, Harrow Weald, Hatch End, Stanmore Park, and Wealdstone - four of these were won by the Conservatives.

“Harrow goes from having two full time MPs to only one, while the rest of the borough is carved up to make up the numbers for seats in Brent and Hillingdon,” said Mr Thomas.

“These changes will just make it easier for the government to keep funding levels for healthcare, schools, the police, and council services in Harrow lower than the rest of London.

“On top of this, these boundary proposals exclude two million people who have registered in the last year. This undermines the fairness in our democracy and leaves millions without a fair say in choosing their MP.”

A statement from the Labour Party said the proposals were “unfair, undemocratic and unacceptable”.

“Constitutional changes should be done fairly and consensually to ensure that everyone is given a voice. That is not the case with these changes, which are more about what is best for the Tory Party,” it continued.

The Boundary Commission’s proposals show how Conservative MP Bob Blackman’s Harrow East constituency could been divided between the new Harrow and Stanmore, and Kenton constituencies.

“The boundary review initial proposals represent a dramatic change to existing boundaries and will need careful consultation. I strongly support the aim of creating constituencies of equal sized electorates,” said Mr Blackman.

“The current boundaries are 20 years out of date in some areas, leaving some people under-represented, so it is important that this is corrected.

“In the case of Harrow, the present suggestions of a Harrow and Stanmore constituency, a Harrow on the Hill and Wembley constituency, and a Kenton constituency, as well as a Ruislip, Northwood, and Pinner constituency, rather than Harrow East and Harrow West, carry a certain amount of logic, although I do have concerns about severing Stanmore and Belmont given their very close community ties, particular for the local Jewish population.

“Overall I look forward to engaging with the process to get the best outcome for everyone. I encourage the public to voice their views as part of this important process.”

Information released by the Boundary Commission on Tuesday shows plans to reduce the number of London’s constituencies from 73 to 68, with boundaries set to shift all over the country. The number of MPs nationally is being reduced from 650 to 600.

A public consultation is now underway, with a two-day hearing to be held in Kenton Hall in Harrow on October 24 and 25 so residents can air their views. The final boundary proposals will not be made to Parliament until September 2018.
