Asda started selling one recently called 19 crimes which is an Australian red. Even people I've offered some to that aren't normally red wine drinkers say it's absolutely gorgeous. You can get a bottle of that for about £6.
When it comes to white, anything that's a Marlborough NZ Sauvignon Blanc is generally top wine. They all taste very similar as they have a distinctive sour taste. Usually they're at least £6, so they're not the cheapest but definitely worth it.
If you like rose wine, the best place to go is Lidl as they actually do a few in the £3-£4 region that are really nice.
