Labour's shadow chancellor Ed Balls has said that Britain "shouldn't flirt" with the idea of exiting the European Union.
He told attendees at the British Chambers of Commerce annual conference that Britain walking out of the EU was the "biggest risk to our economy in the next decade".
European foreign ministers have called on Russia to free female Ukrainian army pilot Nadezhda Savchenko.
Savchenko, 33, was captured by pro-Russian separatists while fighting in a volunteer battalion in eastern Ukraine last June.
The Ukraine government says the separatists took Savchenko to Russia where she was arrested and accused of killing two Russian journalists.
Foreign ministers gathered for a meeting in Brussels held posters which read: "We call the Russian authorities to free illegally abducted Ukrainian Pilot #FreeSavchenko."
European Union rules on what British farmers must grow are a "problem", the Environment Secretary has said.
Liz Truss said she saw the damaging impact of the Common Agricultural Policy on the UK farming industry "all the time".
Truss told the Sunday Telegraph: "There are benefits to being in a single market, but there are serious costs.
"The three crop rule means that Brussels bureaucrats are going to be deciding what our farmers produce, rather than what consumers want, which is a problem."
Mark Carney's comments will not be welcomed in Germany, where there are fears that taxing one part of the Eurozone to pay for another could leave them footing the bill.
ITV News Economics Editor Richard Edgar on the Governor of the Bank of England's comments:
Bank of England Governor Mark Carney praised the European Central Bank for the "boldness" of its plan announced last week to buy hundreds of billions of euros of government bonds to fight the "potentially dangerous" combination of weak growth and falling prices.
But he criticised the eurozone for failing to act on other reforms, including making the single currency area more like the United States, where states cushion one another against economic shocks via federal government transfers.
"It is difficult to avoid the conclusion that, if the eurozone were a country, fiscal policy would be substantially more supportive," he said in a speech in Dublin.
The Governor of the Bank of England launched a broadside against eurozone austerity policies, warning that it was caught in 'a debt trap'.
Mark Carney's comments come as Greece's new Prime Minister confirmed he will be fighting the tight austerity policies placed on the country by the EU.
Since the financial crisis all major advanced economies have been in a debt trap where low growth deepens the burden of debt, prompting the private sector to cut spending further. Persistent economic weakness damages the extent to which economies can recover. Skills and capital atrophy. Workers become discouraged and leave the labour force. Prospects decline and the noose tightens.
As difficult as it has been, some countries, including the US and the UK, are now escaping this trap. Others in the euro area are sinking deeper.

He says the union's founding principles are all well and good, but acknowledges that some feel it is now "more about people we've never voted for, or heard of, making laws that affect our lives".
"Is renegotiation required or are things broadly fine as they are? Should we leave altogether? Is our influence enhanced of diminished in the union?"

David Cameron said he agrees with Sir John Major after the former prime minister suggested the EU was often seen as showing a "lofty disdain" for British concerns.
During a speech in Germany, Sir John put the chance of a British exit from the European Union at "just under 50%" and warned it would become a reality unless there is genuine reform.
When asked about Sir John's speech, Cameron said, "I agree with what he said."
"When countries in Europe have difficulties that need to be addressed, Europe needs to have the flexibility to address them," he said, before describing Sir John's speech as powerful, important and timely.
