I don't recall a right to veto
There is unanimous agreement required in a limited number of policy areas in the Council of the European Union which represents the member states' governments (the European Parliament represents the citizens of the EU).
EU rules currently require the unanimous agreement of member states on certain “sensitive matters”, such as common foreign and security policy, citizenship, EU membership, EU finances, and some aspects of tax policy, justice and home affairs, and social protection.
When we first joined the EU there were more policy areas that required unanimous agreement but these policy areas were reduced with each new treaty. Last year there was an attempt to end all veto rights;

In addition there has been what is known as 'competence creep', e.g. the expansion of past agreements/legislation by the European Commission or ECJ - beyond what was originally agreed or intended.
I do recall that the percentage of votes that went our way was around 90%
That was in the Council although ministers often agreed to things they were not really happy with or agreed to something less restrictive than originally proposed by way of consensus. I think the votes in the European Parliament were nearer 70% our way (2009 - 2014).
And it would have been higher if people like farage had turned up to vote - things like fishing - his absence make a detrimental difference to the UK
Presumably that was on one of the committees rather than in the Parliament where there are over 700 MEPs. How many votes did we lose by on fishing?
