Ratings agency Standard & Poor's said today that British Prime Minister Theresa May's decision to call a snap national election on June 8 might increase the odds of a good Brexit deal for Britain, Reuters reports.

S&P, a longtime critic of Brexit and its negative impact on the UK economy, said a larger parliamentary majority for May's Conservative Party after the election may give her more flexibility to reach a "viable" Brexit deal with the EU.

"Nevertheless, there are risks surrounding both the election -- for example, if voters vote on the basis of Brexit as opposed to on traditional party lines -- and the Brexit negotiations," S&P said in a statement.

"We further think Brexit will continue to create challenging political and constitutional issues around the unity of the United Kingdom, especially if it results in a second referendum on Scottish independence or increases tensions around Northern Ireland," it added.

S&P cut Britain's AAA credit rating by two places to AA shortly after last June's vote to leave the EU.
