LONDON — A quarter of voters say they would consider voting for the Independent Group of MPs who broke away from the Conservatives and Labour Party last week, according to a POLITICO-Hanbury poll.

The results are a boost to the group of 11 MPs who now sit together in parliament as a new grouping and have said they are looking at setting up a new political party, with a leader and policy platform, ahead of the next election.

On Friday, the group announced the roles each of the members will play. “We are not a political party and therefore do not have a leader," said ex-Labour MP Chuka Umunna, who is now group spokesperson.

“Our team is diverse and drawn from different backgrounds, including a former teacher, social worker, lecturer, entrepreneur, solicitor and GP. We intend to draw on all the talents and experiences of our group, as we seek to change politics and give the British people a proper alternative to the broken politics being offered by the main political parties," he said.

Worryingly for Labour leader Jeremy Corbyn, the poll suggests that it is his party's supporters, younger voters and Londoners who are most tempted of the two major parties to switch their support to the new Independent Group (TIG), according to the survey of 2,006 adults that was conducted between February 22 and 25.

Overall, 32 percent of Labour supporters (based on their declared future voting intention) say they are either likely or very likely to vote for a TIG candidate if they stood in their constituency. That compares with 29 percent who said they are either unlikely or very unlikely to do so.

By contrast, just 19 percent of Conservative supporters said they are either likely or very likely to vote for a TIG candidate, with 51 percent saying they are either unlikely or very unlikely to do so.

All 11 MPs in TIG back a second referendum on Brexit, and the favorable polling for the breakaway group — as well as the threat of more defections — may have contributed to Corbyn's decision this week to back that position.

The group also poses a potential threat to the centrist Lib Dems, who have long backed a second referendum — 41 percent of their supporters said they are likely or very likely to vote for a TIG candidate, with 23 percent saying that is unlikely or very unlikely.

The poll results suggest support for TIG comes mostly from the young. Forty-seven percent of 18-24 year olds approve of the formation of TIG, compared with 14 percent who disapprove — a net score of plus 33 percent, according to the poll.

This support steadily decreases with age. Just under a third — 32 percent — of over 65s approve of the new grouping, compared with 30 percent who disapprove.

Within just a few days of TIG forming, the group has already achieved impressive cut-through with voters. Of those who were surveyed by Hanbury Strategy for POLITICO, 62 percent have heard either “a lot” or “a little” about TIG compared with 24 percent who have heard “nothing.”

This rises to some 72 percent of Londoners having heard of the new political group. Yet only 55 percent of those living in Scotland have heard about TIG.

In London, 17 percent of voters said they would be “very likely” to vote for the new grouping if they put up a candidate in their constituency. The equivalent figure for the east of England is 12 percent, while it is less than 8 percent in every other region of the country.

Among the new roles for TIG members, Ex-Labour MP Chris Leslie will be spokesperson for treasury and trade; former Tory MP Anna Soubry will speak on Brexit and justice; and Luciana Berger, another former Labour MP, will cover home affairs, health, and digital and culture.
