The situation in Harrow East and Harrow West before the General Election

The incumbent Labour MP Tony McNulty is facing a strong contestant the Tory candidate Bob Blackman.

An independent MP candidate, Professor Tim Briggs, medical director at the Royal National Orthopaedic Hospital, recently withdrew from running in this year's General Election.

But Mr McNulty, the Harrow East MP is still facing a tough fight in the wake of the boundary changes.

Other candidates contesting for the seat are the Lib Dem's Nahid Boethe, the Green's Sarah Kersey, and UKIP's Abhijit Pandya.

The Harrow West sitting MP Gareth Thomas, is challenged again by another Tory candidate Dr Rachel Joyce, who has worked as an NHS doctor for the past 21 years.

She pledges to open up the Stroke unit at the Northwick Park Hospital, save Mount Vernon Cancer Unit from being shut, and also oppose the post office closure.

Meanwhile, the Labour MP Mr Thomas has been campaigning hard to set up a new police station in Harrow and has pledged to retain the number of Safer Neighbourhood Teams.

A long time campaigner, the UKIP's Harrow West candidate Herbie Crossman has also thrown himself into the race, claiming taxpayers have paid too much money to bureaucracy and European red tape.

Other contestants are Harrow councillor Chris Noyce from the Lib Dems, Rowan Langley from the Green.

Nevertheless, Mr Thomas is believed to enjoy a boost by the boundary changes bringing more Labour voters into his constituency.
