The answer to this question depends entirely upon the nation in question; almost all modern democracies lack any provision for a power of veto at all, and the rules of the power of veto differ from nation to nation.
In the United States, the President - who exercises the power of the executive branch - holds the power of veto, which he has the right to exercise (provided he has valid reasons for opposition to a law) unless Congress over-rules him with a supermajority. Many European nations with a President also have the power of veto, but in every case this power is much more limited. In France and Italy for example, the executivecan refuse to approve a law, but the legislature can over-rule this by passing the law for a second time with a normal majority vote. In almost every nation in the world, it is the executive branch that has this power.
The United Kingdom is, however, a major exception. In theory, the Monarch holds the power of veto over any law, but this power has only been exercised once since the unification of Great Britain in 1707 (and it was exercised in that year). Though the Monarch no longer has any executive functions, they are nonetheless officially the head of the executive branch.
Uniquely however, the United Kingdom also gives the power of veto to its legislative branch, and this is a power that is still - albeit rarely - exercised today. The House of Lords, which is the upper house of the UK's bicameral Parliament, has the power to veto a law, but this veto may only last for one full year, after which the law is considered to have been passed. Furthermore, the House is forbidden - both by law and unwritten convention - to veto any law a party promised to pass in its manifesto, which means it has few opportunities to exercise this power on major items of legislation. Some question whether or not this can truly be considered a veto then, given its limited scope and the fact it is legislative, and not executive.
