(Reuters) -Sterling was barely flat against the euro after rising earlier in the session on robust UK data, while it edged lower against a stronger dollar.
Britain's economy grew by a much stronger-than-expected 0.9% in November, finally taking it above its size just before the country went into its first COVID-19 lockdown.
Despite a potential leadership change in the country after Prime Minister Boris Johnson party scandal, the pound had recently been immune to political noise, being supported by expectations of rate hikes by the Bank of England this year.
The currency's trade-weighted index rose on Thursday to its highest level since June 24 2016, the day after the Brexit referendum vote.
Sterling fell 0.2% to $1.3681 on Friday, within striking distance of its highest level since Oct. 29 touched on Thursday at $1.3749.

The pound was up 0.01% versus the euro at 83.54 pence, not far from its highest level versus the single currency since February 2020 hit on Tuesday.
UK data "suggests the UK economy might have had a little insulation heading into the Covid-restricted December period," ING analysts said in a note.
"A 25bp BoE rate hike is still priced with an 80% probability for the February 3rd meeting - which will likely keep GBP supported over the coming weeks," they added.
Johnson is facing the gravest crisis of his premiership after revelations about a series of gatherings in Downing Street during COVID-19 lockdowns.
According to Berenberg economist Holger Schmieding, "a conservative successor (of Johnson), for instance, Chancellor Rishi Sunak or Foreign Secretary Lizz Truss, would likely pursue roughly similar policies but in a much less erratic fashion."
"A calmer approach could benefit UK markets and domestic business investment," he said.
But, "to bolster his chances to stay in office, Johnson may be tempted to take a particularly hard line against the European Union, for instance on Northern Ireland or fisheries", he added.
British Prime Minister is facing a revolt by grassroots Conservative supporters who want him to resign.
"If political change does not herald policy change, markets do not care," said Paul Donovan, chief economist at UBS.
