Opposition parties have expressed "satisfaction" with their performances in the European elections.
Shadow chancellor George Osborne told the BBC that the Conservatives could take "quite a lot of satisfaction" from the results.
And Nick Clegg said the Liberal Democrats had "held our own" in the polls.
The Conservatives came first in the European elections with 28.6 per cent and out-polled Labour in Wales, but only picked up one extra seat.
The Liberal Democrats came fourth with a 14 per cent share of the vote, down one per cent from the last European elections.
Osborne described the Tory results as "pretty successful".
"If you take it combined with the local elections, we have won in parts of the country where we have not won for many years," he said.
"We have a massive lead over the Labour Party, our principle rivals at the next general election and we have picked up MEP seats.
"Given all the problems that all the major parties have had with expenses, but unlike the Liberal Democrats and the Labour Party who both saw their vote share fall, we actually saw our vote share increase."
He continued: "It is something we can take quite a lot of satisfaction from. Let's be clear, we did pretty well. We are going to form a strong group in the European Parliament."
Clegg told BBC Radio 4's Today programme that the Lib Dem share of the vote had gone down "marginally" and the party had gained one extra MEP. "We held our own," he said.
But he expressed his dissatisfaction that the BNP had gained two seats in the European Parliament.
"I think that we need to be completely uncompromising about the BNP itself," he said.
"It is a party of thugs, of fascists. They don't provide any hope. They don't provide answers. They don't provide solutions to people's problems."
