Russia鈥檚 bullying of its neighbours illustrates why the 海角视频 must keep its nuclear deterrent, according to a Midland MP.

Shadow Foreign Minister John Spellar (Lab Warley) said Russia wasn鈥檛 just threatening the Ukraine but also Baltic states.

But in a sign that historic rows over nuclear weapons haven鈥檛 been entirely banished from the Labour Party, he clashed with one left-wing backbencher who called on .

Paul Flynn, who represents Newport West in Wales, pointed out that the general election on May 7 could result in a hung Parliament in which Labour depended on the support of SNP MPs 鈥 who oppose renewing the Trident nuclear weapon system 鈥 to form a government.

Regardless of who is in power, the Government will have to decide next year whether to go ahead with building new submarines to deliver nuclear warheads, at an estimated cost of 拢25 billion.

A new warhead, costing an estimated 拢6 billion, will also be needed.

Mr Flynn told the Commons: 鈥淲e cannot hold back terrorism with nuclear weapons. We cannot hold back global warming with nuclear weapons. We cannot provide clean water to our planet with nuclear weapons.鈥

But Mr Spellar replied: 鈥淢y honourable friend the Member for Newport West repeated what has been said in other debates that have been based on the response to many of the very real contemporary threats that we face, such as terrorism, insurgencies, cyber-attacks and climate change.

鈥淥f course, they were never designed for that purpose. That is not their role. They are focused on state-on-state conflicts.

鈥淚n Europe, given the increasing assertiveness of Russia, we are starting to see the re-emergence of that scenario.鈥

He added: 鈥淚t is not only the actions in Ukraine that are causing concern; they are merely the most extreme symptom of a number of problems that have been manifesting themselves.

鈥淭here are, for instance, increasing pressures on countries in the 鈥榥ear abroad鈥, especially the Baltic states.鈥

Russia had tested the military capabilities of the 海角视频 and other European countries by sending planes close to 海角视频 airspace, he said.

Mr Spellar said it was 鈥渋mportant for Britain to play a constructive role in working for a nuclear-free world by not removing itself from the equation through nuclear disarmament鈥.

He added: 鈥渙urs is not a unilateralist party.鈥

Mr Flynn said Labour should be ready to do a deal with the SNP 鈥 and warned that Labour MPs would not agree to a 鈥済rand coalition鈥 with the Conservatives, an idea suggested as one potential option by Birmingham Edgbaston MP Gisela Stuart.

He said: 鈥淎lthough I hope and will do all I can to make sure that colleagues in my party in Scotland are re-elected , the message I see day after day is that we are likely to have a group of people here who have put the ending of Trident at the top of their agenda.

鈥淭hat will be a very significant change in this place. The suggested alternative of a grand coalition, if it went ahead, would not include many Labour members.鈥
