Bookies are convinced the Conservatives will win every single Kent seat next week - wiping out Labour in the county.

Paddy Power thinks Labour is odds on to lose all its seven seats to the Tories on May 6.

The Tories are so far ahead in some seats, according to Paddy Power, that punters would have to lay out £750 just to win £1 back.

Darren Haines, spokesman for Paddy Power, said a Labour wipeout in the county was on the cards.

He added: "While the Conservatives are favourites for a national win, no-one knows by how much whereas in Kent, it looks like they are potentially in a position to sweep the board.

"It could be a swathe of blue - they are odds-on in every constituency.

"In some, like Ashford, they are such racing certainties that you would have to bet £500 just to win one pound back."

The one Labour-held marginal where there could be a tighter contest based on the odds is Chatham and Aylesford.

There, the Conservatives are 1/3 on to win the seat from Labour, who are 2/1 to hang on.

"If the betting is anything to go by, Chatham and Aylesford looks like being the closest battle," said Mr Haines.

Labour is also odds-on to lose its safest seat, Dover, with the Conservatives priced at 4/11 to oust Labour, who are 2/1 to retain what on paper is their safest Kent constituency.

"Dover is proving a very popular as a constituency bet and the prices show how Labour has lost a lot of support in the area," said Mr Haines.

For those who fancy the Liberal Democrats to finally make a long-awaited Parliamentary breakthrough in Kent, the odds suggest they have only an outside chance.

The party's best prospects appear to be in Maidstone, where they are 8/1 to win the seat from the Conservatives, who are favourites at 1/40.

In Folkestone and Hythe, the party is priced at 9/1 to cause an upset and take away the seat that has been held by former Conservative leader Michael Howard for 27 years.

"The Lib Dems have an outside chance in one or two places but they are not getting much support."

Whatever the outcome, bookmakers say that they expect a record-breaking £25m to be bet on the election.

"It really has caught peoples' imagination particularly since the first of the leaders' debates," said Mr Haines.
