Boundary changes could mean Hugh Robertson and Norman Baker at risk
Members of the public worried about the security of their own job, at a time of rising unemployment, may not have a great deal of sympathy for MPs - but today is a red letter day for all but 77 of the 650 members of parliament.
In the biggest shake up of the system in a generation, proposed changes by the Boundary Commission recommend the creation of new, larger, parliamentary constituencies.
Under the scheme the number of seats in the Commons would be cut from 650 to 600 by 2015.
The size of seats would also be made more equal with roughly 76,500 voters per constituency.
So how will that affect the political make up of the South East?
The most high profile casualty would be the Olympics and Sport Minister Hugh Robertson.
The proposals would see his Faversham and Mid Kent constituency disappear, with its electorate being divided between Canterbury and a re-shaped Tonbridge constituency.
Speaking to the BBC earlier, Hugh Robertson said: "Clearly on a personal basis it's extremely disappointing."
He said he was born in the constituency and has lived there all his life but despite that he does support the policy and believes there should be fewer MPs in parliament.
Other planned changes in Kent include the creation of a new Margate and Ramsgate constituency that would contain the resort towns of Margate, Broadstairs and Ramsgate.
The Thanet North seat would become a new constituency named Herne Bay, which would take five wards from Canterbury.
Another significant change would be to Helen Grant's Maidstone and the Weald constituency.
The proposals would mean a more compact Maidstone constituency, containing only Maidstone wards.
'Sceptical about reduction'
The existing Tonbridge and Malling constituency, represented by Sir John Stanley, would be significantly reconfigured.
Under then plans it will include ten wards from the existing constituency and take in ten wards from Maidstone, Faversham and Maidstone and the Weald.
Another South East minister at risk from these plans is the Transport Minister and Lewes MP Norman Baker.
Speaking to me earlier, he said: "When I think of the hours I work, I can't work any more. So I am sceptical about reducing the number of MPs."
He also said he didn't think people in Lewes would be happy about "being lumped in with Brighton".
The commission says that due to the small electorates of the neighbouring Lewes and Brighton Kemptown constituencies they propose a Lewes and Brighton East constituency.
Elsewhere in Sussex, there are plans for an entirely new Uckfield constituency, that would take in 12 wards from the existing Wealden constituency.
A new Bexhill constituency would be made up of almost half of the existing Bexhill and Battle constituency and also include wards from the existing Wealden constituency.
As a result of the changes in East Sussex, there would be an entirely new constituency, called The Weald, which crosses the boundary between Kent and East Sussex.
The commission says that due to the similarity of both areas, and the geographical nature of The Weald they thought this was the most suitable place to create a cross boundary constituency.
Some constituencies would remain largely unchanged - including Rehman Chishti's seat in Gillingham and Rainham and Gordon Henderson's seat of Sittingbourne and Sheppey.
These are of course only proposals and they will now go out to consultation over the next three months.
The Boundary Commission wants people to get in touch to let them know if they agree with the plans for the South East and if not what alternatives they propose.

Once the public has had its say the Boundary Commission will publish revised proposals next year which will also be subject to exhaustive consultation before finally being submitted to Parliament for approval by October 2013, in time for the election in 2015.
That may seem like a long way off but, for MPs, like Hugh Robertson it means if they want to remain in parliament they will have to contest other constituencies.
So while the future of some of our politicians is uncertain, one thing which is certain is there will be even more jostling than usual for position among MPs ahead of the next election.
