Stocks in London ended in the red on Tuesday as gloomy PMI data from Europe and the US cast a shadow over the market and fears over a potential windfall tax hurt energy companies.

The FTSE 100 index closed down 29.09 points, or 0.4%, at 7,484.35. The mid-cap FTSE 250 index closed down 296.36 points, or 1.5%, at 19,849.82. The AIM All-Share index closed down 8.56 points, or 0.9%, at 955.29.

In the FTSE 100, Barclays ended up 3.5%, after the bank launched its delayed share buyback programme.

Barclays said it will kick off a £1.00 billion share buyback programme on Tuesday. The programme, initially announced in February, had been delayed in March after the bank admitted it sold more products to investors than it was allowed to.

Glencore closed up 1.8% after the commodities house said in response to media enquires, that it expects to resolve its US, UK and Brazilian investigations this year.

Glencore said it will appear in court in the US and UK on Tuesday in connection with proposed resolutions of the relevant investigations. Glencore expects to issue an announcement following the conclusion of these court hearings, it added.

Bloomberg on Tuesday reported that Glencore will pay $1.5 billion to settle US and UK investigations into alleged wrongdoing, according to people familiar with the matter.

At the other end of the large-caps, ad agency WPP ended the worst performer, down 9.3%, in a negative read-across from US social media platform Snap which issued a profit warning.

The Snapchat owner was down 41% in New York after warning it would struggle to meet its own targets for revenue and adjusted earnings in the current quarter.

Last September, Snap teamed up with WPP to launch the AR Lab global partnership, which set out to help brands build augmented reality-based immersive experiences, with a focus on e-commerce.

Royal Mail ended down 4.4% after Peel Hunt downgraded the former state postal monopoly to 'sell' from 'buy'.

Utility and energy firms were also among London's laggards on Tuesday, falling on broker recommendation cuts and also reports of a UK windfall tax which would go above and beyond just hitting oil majors.

A windfall tax is a one-off tax imposed on a company or group of companies and was introduced by Tony Blair's Labour government in 1997.

SSE tumbled 7.7%. Citigroup cut the electricity utility to 'neutral' from 'buy'.

The US bank also cut electricity generator Drax to 'sell' from 'neutral'. Shares in the FTSE 250-listed power generation firm slumped 14%.

Blue-chip Harbour Energy shed 4.6%.

Elsewhere, British Gas owner Centrica lost 7.6%, Frankfurt-listed RWE fell 4.5% and Scottish Power owner Iberdrola fell 0.5% in Madrid.

The Financial Times reported on Monday that UK Chancellor Rishi Sunak is mulling a windfall tax on more that £10 billion of excess profit achieved by electricity generators.

Calls for a windfall tax, particularly on oil majors such as BP and Shell, have intensified as the UK cost of living crisis worsens, and clubbing in electricity generators such as SSE, RWE and Iberdrola's Scottish Power would boost the revenue a potential windfall tax could bring.

In Europe's largest economy Germany, the flash composite PMI inched higher to 54.6 in May from 54.3 in April. The growth was driven by ‘strong’ post-lockdown recovery across the country's service sector.
