A day after the European Union waved goodbye to Britain, some of Europe's poorest nations urged the bloc's leaders not to implement a "sharp and disproportional" cut to their aid money in the next long-term budget.

The European Union provides aid known as cohesion funds to member states in the south and east to help them invest in development and catch up with richer peers to the north and west.

But various proposals by the "frugal" countries, including paymaster Germany in September, seek to reduce the size of the cohesion funds and attach conditions which would predetermine areas where investments should go.
