EU Must Reform For Jobs And Growth - Cameron
David Cameron has called fellow European leaders and urged them to "seize the opportunity" for reform on jobs and growth following the European elections.
In a series of phone calls the Prime Minister urged them to "heed the views expressed at the ballot box" over recent days.
His intervention came ahead of today's Informal European Council dinner in Brussels, where leaders are expected to discuss the results of the European poll.
Many European leaders, including Mr Cameron and Denmark's Helle Thorning-Schmidt, saw their support fall away to anti-immigration parties such as UKIP.
German Chancellor Angela Merkel also lost votes to Alternative For Germany, a party opposed to the euro.
Mr Cameron told leaders, including Ms Merkel and Sweden's Prime Minister Fredrik Reinfeldt, that the results of the poll underlined the need for reform, in particular on job creation and economic growth.
"The PM has been making the point in these conversations that leaders should seize the opportunity of Tuesday's dinner to heed the views expressed at the ballot box," said Downing Street.
"The turnout and results in the EP elections have underlined the need for reform to ensure that the EU is doing more to deliver what voters care about: jobs, growth and a better future."
A senior diplomat said the informal dinner will look at the EU Council's priorities over the next five years, and discuss the likely impact of the confusing mosaic of political interests elected to the chamber.
The diplomat said no names for a potential president of the Commission would be discussed, and that the process of picking a successor to Jose Manuel Barroso could take weeks, not days.
The leaders might use the dinner to slim down the Council's "to do" list, in order to concentrate on encouraging growth and employment, so restoring faith in the institutions of the European Union.
Parties which campaign against the European Union, or its current structure and priorities, doubled their representation in the parliament with a humiliation for the French President Francois Hollande.
Mr Hollande's Socialist Party secured nearly half as much support as the right-wing Front National.
He has signalled his intention to press ahead with reforms in France, while also pushing for the EU to prioritise growth and jobs.
"I am a European, it is my duty to reform France and re-focus Europe," he said in a message broadcast on French television.
The EU Council is also expected to discuss developments in Ukraine, where presidential elections were held at the weekend.
