Michael Thornton won the Eastleigh by-election

by business editor Trevor Sturgess

The new MP for Eastleigh has given up his job with a Medway business after his sudden move to Westminster, it can be revealed.

Michael Thornton, who held the Hampshire seat for the Liberal Democrats with a majority of more than 1,700 yesterday, has been hailed as a tax crusader and business champion by his boss.

Shaun Murphy, managing director of Portal Tax Claims, based on Medway City Estate, said: "I'm losing a great staff member, but the Lib Dems are gaining a true business champion."

Portal specialises in capital allowances, advising firms on how to gain the maximum financial benefit from government rules.

Mr Murphy, pictured right, wondered if Mr Thornton would use his maiden speech in Parliament to bang the drum for capital allowances.

"Mike has been a great advocate for this overlooked, complicated but very necessary tax break for business and we hope to see him continue to fight the good fight in Parliament.

"The Lib Dems now have a top tax specialist in their midst and the opposition face a tough challenger the next time there's a debate on tax in the House.

"He's coming straight from the coalface and following a very successful career helping hundreds of businesses secure millions in tax rebates."

He added: "We're sorry to lose him but no doubt the tax man will take a different view on seeing the back of a sharp opponent."
