here's a few you can start with:

pull out of the war      pacifist or just the afghan situation? afghanistan mainly atm, im not aware of others
abolish tuition fees      dont agree good for you, i believe in having an education system thats free (i.e state funded) from nursery to uni
proportional representation      dont agree you dont want your vote to be more effective?
proggressive taxation        elaborate a system that is more redistributive than our current one
more funding for the NHS/Education system      more cash wont make any difference, new thinking required true, but idk if we agree on what sort of thinking
abolish faith schools       agree good!
legalise less dangerous drugs      disagree why? from what i understand, many are less harmfull than alcohol or smoking
close tax loopholes        such as? idk the specifics, but they get mentioned alot on tv and in the paper
better public transport (trains, buses, etc)       whats the motivation here? what do you think? less pollution i would hope
abolish the monarchy          whats the motivation here?  (its just a symbolic act and will make no difference) there pointless and a waste of money, plus if we call ourselves a democracy, they need to go
make the lords elected (if not fully, then atleast like 75%)        somewhat agree somewhat?
proper action on climate change (more renewable energy, no nuclear either, its not safe or viable from what ive read, we probably dont need nuclear weapons either, so they can go too)      nuclear energy is our only way out, pissing about with other stuff will take too long.. we dont have that time, keep nuclear weapons. wrong, from what ive read, nuclear energy is impossible to dispose of the waste and is less not more viable than other things, why do we need nukes where our allies like the US have them? worst comes to worst, we just ask for there help, though i think its unlikely we would need too
