U.K. Labour Party politician and contender for the leadership of the party, Liz Kendall, has attacked the Greek government, which has so far failed to reach a compromise with creditors, comparing their methods to "fantasy".

Kendall, who is up against three other Labour politicians in a fight to win leadership of the party, which suffered a bruising defeat in the U.K. general election, said the situation with Greece posed a "historic moment for Europe".
