Pendle MP, Gordon Prentice, is devoting a section of his website to the Conservatives, publicising their newsletters and other campaigning material.

Speaking from Westminster earlier today, the MP said: "The published accounts of the Pendle Conservative Association do not tell the whole story. They are spending as if there is no tomorrow."

"Their tabloid newsletters are delivered by the Royal Mail to all 37,000 households in Pendle. No other political party can match their spending power."

"The Conservatives have received millions from Lord Laidlaw, a self confessed tax exile living in Monaco. Lord Ashcroft is also a huge donor. But Ashcroft refuses to say whether he is a tax exile or not."

"He was elevated to the peerage in 2000 on the recommendation of the then Conservative leader, William Hague, and after promising to bring his tax affairs on shore."

The House of Lords is likely to debate amendments to the Political Parties and Elections Bill on Monday 15 June which would close the so called "Ashcroft loophole" which allows people who are not UK residents for tax purposes to bankroll political parties.

Last week the Pendle Conservatives threatened legal action against Mike Warner, a former Lib Dem councillor in Pendle, who has raised questions about their accounts.
