(There will be no London stocks report on Monday on account of Queen Elizabeth's state funeral)

* GBP trades below 1.14 for first time since 1985

* UK retail sales plunge, underlining risk of recession

* FTSE 100 down 0.6%, FTSE 250 off 0.5%

* Both indexes mark weekly losses

Sept 16 (Reuters) - UK stocks closed lower on Friday, hurt by the risk-off mood gripping global markets and weaker-than-expected domestic retail sales data that highlighted growing recession risks at home.

The blue-chip FTSE 100 slipped 0.6% while the domestically-focussed mid-cap FTSE 250 shed 0.5%.

Both the indexes marked sharp weekly losses as appetite for equities worsened worldwide on worries that aggressive monetary policy tightening by global central banks would choke growth.

The FTSE 100 found little relief as sterling fell to a fresh 37-year low against the dollar on the 30th anniversary of "Black Wednesday." A weakening domestic currency typically supports the export-heavy index, which houses several global companies that draw revenue overseas.

"The country is heading towards recession if it isn't already in one," said Frederique Carrier, head of investment strategy at RBC Wealth Management.

"Given the challenges ahead, we think it is prudent to take some profit in UK equities," added Carrier, who recently downgraded the market to "underweight" while staying cautious on domestic stocks.

The Bank of England will meet next week, part of a packed week of central bank meetings. Market pricing indicates a slightly higher chance of a 75-basis-point hike than a 50-basis-point jump.

"Investors are doubling down on the story that inflation is very strong and persistent and the central bank's aggressiveness to deal with it risks weighing on the global economy," said Oliver Allen, market economist at Capital Economics.

Adding to pressure, FedEx Corp withdrew its financial forecast and flagged a global demand slowdown, denting stock markets and shares of delivery firms worldwide.

British postal company Royal Mail closed 8% lower, also hit by a J.P.Morgan downgrade to "neutral".
