LONDON, Sept 23 — Sterling held steady today as investors awaited the British Supreme Court decision on whether Prime Minister Boris Johnson misled Queen Elizabeth over proroguing parliament, as well as whether Johnson will be able to find some compromise over Brexit at the United Nations General Assembly in New York.

Expectations that some progress in Brexit negotiations will be made at the United Nations were low, however, leaving little room for disappointment for pound traders in case it does turn out that Johnson fails to gain some ground from European leaders, analysts said.

"We are sceptical of much in the way of progress being made and on top of that there is also the risk of PM Johnson having to cut his trip short to return to London if the Supreme Court decision goes against the government,” said MUFG analysts in a note to clients.

Johnson suspended — or prorogued — the British parliament for five weeks until October 14, which Scotland’s highest court of appeal ruled unlawful. But Johnson appealed the Scottish decision to the Supreme Court, which is expected to announce its decision early this week, analysts said.

If the Supreme Court were to rule against the government, it would increase political uncertainty in the country and "weigh on sterling a little,” said Jeremy Stretch, head of G10 forex strategy at CIBC.

The collapse of British travel firm Thomas Cook will also likely put some pressure on the British currency as it highlighted the weakness of the British retail sector, Stretch said, adding that he sees "a drift lower for cable (pound/dollar) for now.”

Sterling/dollar will likely trade around "US$1.23 (RM5.14) in the short term,” Stretch said.

The pound was down 0.3 per cent in mid-morning London trading at US$1.2435, having dropped earlier to a six-day low of US$1.2424, mostly due to broad-based dollar strength.

The dollar index was up 0.2 per cent at 98.74 after rising earlier to 1 ½ week high of 98.832.

Against the euro, the pound was flat at 88.265 pence.

The British pound had pulled back from a two-month high and fell on Friday after Irish Foreign Minister said that London and the European Union were not yet close to a Brexit deal. — Reuters
