Social Issues
Abortion: I'm staunchly pro-choice. It's the mothers decision what she does with her body.
Church and state: Keep the two completely separate. If you want to follow a religion, follow it, you don't need the government to "enforce" or "endorse" a religion for you to do that. Get religion out of schools (replace "R.E." with something more productive), abolish state run schools which have religious affiliation.
Gay Marriage: Legalize
The Smoking Ban: Keep it and keep it as it is. There's no need to expand it or abolish it.
Euthanasia: Legalize it.
Prostitution: Illegal
Embryonic Stem Cell Research: I don't have a problem with it. The pros far outweigh any cons.
Immigration: I personally don't have a problem with the current system, although i'd support some stricter rules and regulations simply to put a stop to the rise of the far-right.
Economic Issues
Taxes: Tax cuts for those earning less than £150,000 a year
Welfare: Support
Healthcare: Increase funding for the NHS.
Education: Massively increase funding in education. As above, abolish religiously aligned schools. Encourage lessons to develop citizenship. Abolish tuition fees! Keep the Education Maintenance Allowance (E.M.A) and maybe extend the limit to £40,000 income to receive it. Make Sixth Form education compulsory.
Minimum Wage: Keep it and raise it.
Infrastructure: Introduce congestion charges in all major cities, but massively cut prices for public transport.
Energy Policy: Build more wind farms and put up solar panels. Take advantage of tidal power and other renewable resources.
Foreign Issues
European Union: Further intergrate with Europe although I oppose a federal "United States of Europe". Oh, and President Blair
Iraq: Withdraw troops now. Blair was stupid for going along with GWB.
Afghanistan: Increase troop numbers there.
Military Involvement: Attack only if attacked or directly threatened. Don't blindly follow the US like with Iraq.
Military Budget: Cut it.
Domestic Issues
Devolution: Support the assemblies in Wales, Scotland and Northern Ireland as long as Scottish, Welsh and Northern Ireland MPs aren't allowed to vote on England-only matters OR form an English Parliment just for England issues and keep the current Houses of Parliment for UK-wide issues.
Scottish/Welsh Independance: Oppose! Keep the United Kingdom united.
Voting and elections: Keep the voting age at 18. Allow yearly referenda similar to the US state ballot questions/propositions etc. Keep the FPTP system. Give constituents the ability to re-call their MP. Democratically elect members of the House of Lords. Install a "registered voter" system similar to the US so that party members can elect their party leader.
Monarchy: Abolish it completely. Become the United Republic and let the public elect the head of state.
