Markets have shown signs of relief as Shabana Mahmood is increasingly favored for the role of Chancellor over Ed Miliband, according to emerging speculation about incoming Prime Minister Andy Burnham's cabinet. Miliband is reportedly being considered for Foreign Secretary.

This potential shift has been met with positive market reactions, with the Pound gaining ground and UK borrowing costs easing, reflecting a preference for Mahmood's perceived centrist economic approach. Conversely, Miliband, whom critics have described with 'Soviet' views, is seen by some as a platform for a global clean energy push, a role allies suggest would leverage his "high reputation" on the world stage.

Miliband's allies have promoted his credentials for high office, citing his experience as Net Zero Secretary and his leadership in climate negotiations. However, some in the business community have expressed concerns about his potential economic policies. A Bloomberg survey indicated low investor support for Miliband as Chancellor, with Mahmood faring only slightly better.

The speculation comes as the UK economy faces challenges, with official data showing GDP growth stalled at 0.1 percent in May, following a 0.1 percent drop in April. This economic backdrop, coupled with comments from Burnham suggesting potential tax increases, has fueled market anxiety. Conservative leader Kemi Badenoch criticized Labour's focus on taxation, stating the country faces "another summer of chaos."

Burnham's team has maintained a tight-lipped stance on cabinet appointments ahead of his formal assumption of office on Monday. Concerns have been raised about his mandate and communication style, as he has spoken infrequently in Parliament and opted for selective engagement with the media. His recent comments in a discussion with Gary Lineker, where he indicated openness to increasing the tax burden, have drawn particular attention.

Economists have highlighted the vulnerability of the UK economy to global events, particularly the conflict in the Middle East, which has disrupted supply chains and driven up energy costs. Suren Thiru, ICAEW Chief Economist, noted that prolonged hostilities could further damage the economy and reduce the new Prime Minister's fiscal flexibility. Samuel Edwards of Ebury added that uncertainty over the future Chancellor and the government's economic direction is a concern for businesses.

Economists at Pantheon Macroeconomics project that the May growth figure puts the economy on track for 0.3 percent growth in the second quarter, a slowdown from the first quarter. The ongoing volatility in energy prices is expected to continue dampening economic activity.

Despite the economic headwinds, a Treasury spokeswoman stated that the current government has implemented the right economic plan, leading to strong growth and restored stability. Forecasts suggest the UK will be the fastest-growing European G7 economy in the coming years, with inflation steady and borrowing expected to be below the G7 average.

Questions remain about other potential appointments, with Miatta Fahnbulleh reportedly being considered for the Net Zero brief. The future roles of Yvette Cooper, the current Foreign Secretary, and the Home Office portfolio are unclear. Any significant shifts in top positions, particularly a reduction in the number of women in senior roles, could face scrutiny.

A spokesman for Burnham stated that no final decisions have been made regarding his cabinet. However, an ally told the Financial Times that Mahmood's appointment as Chancellor is a certainty.
