The newly appointed deputy leader of the United Kingdom Independence Party has described the party's election campaign as "very successful", despite not winning any seats, claiming that the party succeeded in its objective of forcing a hung Parliament.

Yesterday UKIP appointed Lord Christopher Monckton Brenchley as its joint deputy leader. Lord Monckton unveiled the party's policy on climate change earlier this year, after joining the party in 2009. He is one of the world's best known climate change sceptics and was a former policy advisor to Margaret Thatcher.

The leader of UKIP, Lord Malcolm Pearson of Rannoch, said, "I am extremely happy that Christopher Monckton wants to be more involved with the Party. He will be helping me to develop our strategy for the future. David Campbell Bannerman remains joint deputy leader and head of policy."

During the election Lord Pearson said that his aim for UKIP was create a hung parliament and force the major parties to address the issue of Britain's membership of the European Union.

While UKIP failed to win any seats a detailed look at the election results suggests they may have cost the Conservative Party up to 21 seats. Had those seats gone Tory, the party would have had a majority of one and would not have needed to go into coalition with the Liberal Democrats.

Lord Monckton said, "I am delighted that Malcolm Pearson has taken this step. I very much look forward to travelling around the country meeting constituency associations and their members and working with them to continue the rapid growth of UKIP.

"Malcolm has led us to a very successful result in the General Election. We hung the Parliament because the Conservatives sullenly and unwisely refused to give the British people a vote on whether Britain shall remain a mere satrapy of the dismal European dictatorship or whether we shall once again be the proud and independent democracy that once we were.

"My first task will be to build on the Initiative Referendum Bill already tabled in the House of Lords by Lord Pearson and Lord Willoughby de Broke by drafting new, radically democratic constitutions for Britain and for Europe. After 1000 years of inexorable progress towards democracy, in the last 30 years pernicious peculation by Parliament's political pygmies has thrown Britain's democracy away.

"The new written constitutions for our great nation and for our great continent will restore government of the people, by the people and for the people. We, the people, shall rule."
