London stocks were set to rise at the open on Tuesday from the fresh record close hit a day earlier above the 10,000 mark.
The FTSE 100 was called to open around 40 points higher.
Ipek Ozkardeskaya, senior analyst at Swissquote, said: "Oil and defence stocks, along with rare earth metals, have been the biggest gainers from the Venezuela news.
"The UK's energy- and mining-heavy FTSE 100 traded past the 10,000 mark for the second session in a row and closed above that level for the first time."
Investors will be mulling the latest data from the British Retail Consortium, which showed that shop price inflation edged higher in December as food price growth accelerated strongly.
The BRC-NielsenIQ monthly shop price monitor showed a 0.7% year-on-year increase in prices at UK tills in December, up from 0.6% in November.
Food price inflation picked up to an annual rate of 3.3% from 3.0%, with fresh food inflation rising to 3.8% from 3.6% and ambient food inflation increasing to 2.5% from 2.4%.
Meanwhile non-food deflation held steady at -0.6%, with promotional activity ahead of the festive holidays partly responsible for ongoing price falls.
Despite the overall increase in prices, "shoppers still found plenty of value across many Christmas essentials including vegetables, cheeses, and alcohol", according to BRC chief executive Helen Dickinson. "Promotions were also widespread across popular gifting categories, including toys, books, and home entertainment."
However, the BRC said that, despite retailers' best efforts, inflation is likely to "remain sticky" in 2026 as a result of increased public policy costs and regulation.
"2026 must be the year that government works with business to create a policy environment that reduces the pressures bearing down on the industry. This will enable retailers to invest more in keeping their prices down, benefitting households all across the country," Dickinson said.
In corporate news, high street retailer Next lifted full-year guidance on the back of better-than-expected festive trading.
In the nine weeks to 27 December, full-price sales rose 10.6% year-on-year, comfortably ahead of forecasts for a 7% improvement across the entire quarter.
As a result, the company now expects total group sales in the year to 31 January to come in at £6.97bn and pre-tax profits of £1.15m. Next had previously guided for annual sales of £6.87bn and pre-tax profits of £1.14bn.
Rank Group said chief executive John O'Reilly had decided to retire on 29 January and will be replaced on an interim basis by chief financial officer Richard Harris.
The Mecca bingo owner added that a formal search process to identify a permanent CEO would now begin.
